Many homeowners want open-plan living. However, they often feel dread at the thought of the process. Removing the rear wall of your home sounds major. Risky. Disruptive.

When well designed and managed, an open-plan space can avoid turning your home into a building site. In some layouts you can open up the back of the house without needing major steelwork.

This guide covers what happens when you knock through walls, when you need steel, and when you don’t. It also explains how orangeries are made for open-plan living and helps you choose the right structure for your lifestyle.

The Short Answer

  • Open-plan living does not always require removing the entire rear wall.

  • Structural steel is only needed when openings are widened or newly created.

  • A modern orangery is built to the same standards as a flat-roof extension.

  • Orangeries retain more natural light in open-plan layouts.

  • If you create a new opening and fit a door, Building Regulations usually apply only to the steel; if you leave the opening fully open, they apply to the steel and the structure.

  • The right solution depends on layout, light, structure and disruption, not product labels.

The real question is not whether an orangery is a proper room.
It is what structure and layout suit your home and lifestyle best.

At a Glance: Orangery vs Extension for Open-Plan Living

  • Structure
    • Both are permanent extensions built to full Building Regulations.
  • Light
    • Orangeries retain and introduce more light into existing rooms.
  • Roof 
    • Orangery uses an insulated flat roof with lanterns. Extensions may be fully solid.
  • Open-plan layouts
    •  Orangeries are designed to integrate large openings cleanly.
  • Look and feel
    • Orangeries create a feature space. Extensions are more traditional.
  • Disruption 
    • Both require knock-through works if fully open-plan.

If you want a deeper comparison of insulation, comfort and performance, we’ve covered that in detail here.

Each of these points is explained in detail below.

 

 

What Open-Plan Living Actually Means in Real Homes

Open-plan living is not one single layout.

In real homes, it usually means one of three things:

  • Removing an existing set of doors or windows.
  • Widening an existing opening.
  • Removing most or all of the rear wall.

Each option has a very different impact on structure, cost and disruption. Many homeowners assume full removal is the only route. Often, it is not.

Structure and Performance: Why an Orangery Is a True Extension

A modern orangery is constructed to the same standards as any flat-roof extension.

This includes:

  • Proper foundations.
  • Insulated cavity walls.
  • Full compliance with Building Regulations where they apply
  • Permanent, habitable construction.

Our orangery systems use over 200mm of roof insulation, compared to around 150mm in many standard warm-roof systems. This delivers strong thermal performance and stable internal temperatures all year round.

In performance terms, there is no compromise. The difference is architectural design, not comfort or durability.

Roof, Insulation and Heating in Open-Plan Spaces

Heating becomes more important once a house is opened up.

When internal walls are removed, heat moves differently through the home. A well-designed orangery accounts for this from the start.

Key considerations include:

  • Insulation levels that prevent heat loss through the roof.
  • Maintaining warmth in both the new space and the existing room.

Heating layouts that suit larger, connected spaces.
With modern insulation standards, an open-plan orangery can be heated just as efficiently as the rest of the house. There is no inherent increase in running costs when it is designed properly.

Light: Why Orangeries Work So Well for Open-Plan Living

Light is the factor most homeowners overlook.

When you knock through the rear wall of a house, you are not just adding a new space. You are also affecting the light levels in the existing room you are opening from.

This is where orangeries excel.

Features such as:

  • Roof lanterns.
  • Reduced full-height glazing balanced with solid walls.
  • Carefully proportioned openings.
  • Allow light to travel deeper into the original home.

With a fully solid roof extension, restoring lost light later can be difficult and expensive. With an orangery, light is designed in from the beginning – especially when paired with the right glazing.

What really changes when you knock through (and when you need steel)

Knocking through is usually the most worrying part for homeowners. Understanding what actually happens helps reduce that fear.

Structural Support

When you enlarge an opening or remove part of the rear wall, the load above must be supported.

This is done with structural steel.

Steel is required when:

  • A new opening is created.

An existing opening is widened, even by 100–200mm.
Steel is not required when:

  • Doors or windows are removed without enlarging the opening.

Examples where steel is often not needed:

  • Removing French doors to the garden.
  • Removing a kitchen door and adjacent window while keeping the original opening width.

Services and Drainage

Anything fixed to the rear wall must be addressed before knock-through works.

This includes:

  • Downpipes.
  • Waste pipes.
  • Taps and sinks.
  • Electrical points.

Rerouting is usually straightforward. Complexity increases when there are multiple waste pipes or soil stacks, which is why layout planning matters early.

Making Good

After the structural work is complete, finishing work brings the home back together.

This includes:

  • Closing wall cavities.
  • Plastering internal and external surfaces.
  • Screeding floors where walls or doors were removed.
  • Preparing surfaces so flooring and finishes can be installed easily.

The goal is always to leave the space move-in ready, not half finished.

Keeping Part of the Rear Wall vs Full Knock-Through

This is one of the most important design decisions.

As soon as you meet any of the following conditions, costs increase:

  • Widening openings significantly.
  • Introducing large steels.
  • Relocating drainage and services.
  • Creating flush ceiling steel insertions.

Keeping part of the rear wall can:

  • Reduce steel size.
  • Reduce disruption.
  • Lower cost.
  • Still achieve a strong open-plan feel.

Do You Always Need Steel to Go Open-Plan?

No – but you always need proper structural support.

In simple terms:

  • New openings or wider openings almost always require steel or an equivalent structural solution.
  • Keeping the existing opening size can sometimes be done without additional steel, if the original opening was properly supported and passes structural checks.

This is why some open‑plan layouts are significantly more cost‑effective than others: they work with the existing structure instead of fighting it.

Important note: the examples in this guide are for illustration only. On every project we:

  • Survey the property
  • Obtain structural calculations where required
  • Agree the final knock‑through design based on what is safe, compliant and appropriate for that specific house

That’s how we keep costs sensible without taking risks with the structure.

What Changes the Cost of Steel Works

Steel cost is not just about the beam itself.

Key cost drivers include:

  • Size: Larger openings require larger steels.
  • Complexity: Welding to existing steels or complex load paths adds cost.
  • Access: Most steels are carried in by hand. Difficult access may require lifting equipment or, rarely, a crane.
  • Splice joints: Where access is tight, steels can be bolted together in sections to avoid heavy lifting.

Most projects do not require cranes. Where they do, costs can increase by £1,000–£2,000.

Types of Steel Insertion

Ceiling Level

  • Stepped steel: Steel sits below the existing ceiling line. More common and more cost-effective.
  • Flush steel: Steel is hidden within the floor structure above so ceilings run level. This costs more but creates a cleaner look.

Side Supports

Most steels require supporting pillars at each end.

In some cases, windposts can be hidden within wall cavities. This avoids visible pillars but increases cost and is used selectively.

When an Orangery Makes More Sense for Open-Plan Living

An orangery is often the better choice when:

  • You want to open a kitchen or diner to the garden but retain light.
  • You want a feature space that still feels part of the home.
  • You are concerned a fully solid roof will darken the centre of the plan.

Real-world example:
On this project, the goal was to improve flow without losing daylight in the existing home.

  • The orangery was designed with controlled glazing and a lantern.
  • The knock-through was sized carefully to balance openness and structure.
  • Light now travels deeper into the original rooms, not just the new space.

When a Solid Extension Is Still the Right Answer

A traditional extension can be better when:

  • Deep plans require more ceiling space for services.
  • Privacy is a priority.
  • Planning or design constraints limit glazing.

Storage and wall space outweigh light requirements.

Design Rules We Use for Successful Open-Plan Living

  • Preserve or add light into existing rooms.
  • Make homeowners aware of any internal pillars early.
  • Zone spaces for noise and quiet.
  • Ensure natural circulation without creating corridors.
  • Treat the orangery as part of the house, not an add-on.

Common Mistakes to Avoid

  • Knocking through without considering light loss.
  • Assuming steel is always required.
  • Ignoring cost-effective layout options.
  • Skipping proper structural calculations.
  • Treating the orangery as a bolt-on room.

Living in the house during knock-through works

Most homeowners can stay in the house during works. The key is clear sequencing and knowing what happens at each stage of the build.

Typical realities include:

  • Short periods of dust and noise.
  • Temporary loss of access through the rear.
  • Clear sequencing to minimise disruption.

Partial knock-throughs are usually far less disruptive than full wall removal.

Planning and Building Regulations Explained Simply

Planning permission answers one question: can I build it?
Building Regulations answer another: has it been built properly and safely?

f you want a full breakdown of how planning works in 2026, including Permitted Development and Prior Approval, we explain it here.

For open-plan projects, Building Regulations are triggered by structural change, not by the idea of open-plan living itself.

If you only remember one thing, remember this:

  • New or wider openings almost always need structural calculations and Building Regulations sign‑off.
  • Replacing doors/windows in an existing opening is usually simpler, and often cheaper, than creating a brand‑new opening.

What matters most is whether a new opening changes how the house is supported.

When structural calculations and Building Regulations are not required

  • You remove existing doors or windows.
  • You do not increase the size of the opening.
  • You install new doors, such as bifolds, into the existing gap.

In this case:

  • No new structural support is needed.
  • No structural calculations are required.
  • No Building Regulations approval is needed for the opening itself.

This is why some open-plan layouts are simpler and more cost-effective than people expect.

When structural calculations are required

Structural calculations are required when:

  • A new opening is created.
  • An existing opening is widened, even slightly.
  • Load from above needs to be redistributed.

This usually means installing a steel beam.

How Building Regulations apply in different knock-through scenarios

  1. New opening with a steel beam and a door installed (for example, bifolds)
    • Structural calculations are required for the steel.
    • Building Regulations apply to the steel only, not to the new structure as a whole.
  1. New opening with a steel beam and no door installed (fully open plan)
    • Structural calculations are required.
    • Building Regulations apply to:

      • The steel.
      • The surrounding structure.

Fire safety and load paths where relevant.

This is because the opening becomes part of the main habitable space, not a separated room.

The simple rule to remember

  • If you create a new opening and install a door, Building Regulations usually apply only to the steel.
  • If you create a new opening and leave it fully open, Building Regulations apply to the steel and the structure.

This distinction is important, and it is why layout decisions can affect cost and complexity.

Why this matters for homeowners

Understanding this early allows:

  • Smarter layout choices.
  • Better cost control.
  • Fewer surprises once work starts.

It also explains why some open-plan projects feel straightforward, while others require more involvement.

How Precision Handles Open-Plan Projects

Our process removes uncertainty:

  • Site visit and layout review.
  • Light and structure assessment.
  • Options presented, including when not to knock through.
  • Clear costed routes.
  • Fixed-price proposal for the agreed scope.

We will tell you when a solid extension is better than an orangery, and when keeping part of the wall makes more sense.

Final Takeaway

Open-plan living is not about removing walls for the sake of it.

It is about light, structure, comfort and how you want to live day to day.

A modern orangery is designed to make open-plan living work, not just look good.

How much does a 4 x 3m Orangery Cost in 2026?

A realistic cost guide covering specification choices, structural work, and how to budget properly.

last updated Jan 21, 2026

Share with friends

Read time: 5-6 minutes

Many homeowners in the South of England ask the same question when planning an orangery:

“How much will a 4 x 3m orangery actually cost in 2026?”

This guide explains what drives the price, what is included, what is not, and how to plan your budget with confidence.

The Short Answer

  • For a typical 4 x 3m orangery  (approximately 12m²) in the South of England in 2026, including VAT
    • Standard finishes and minimal structural work: approx £30,000–£32,000
    • Higher-spec designs with more brickwork, wider openings or premium finishes: from £35,000+

Below we break down what actually changes these numbers

What Actually Changes the Price?

  • Groundworks & Foundations
    • This is often one of the biggest cost variables.
    • Where deeper footings are required to meet Building Regulations, or where the garden level drops away from the house, costs increase due to additional excavation, concrete and build-up. We’ve seen this add £1500-2000 when the ground falls away fast from the house. 
    • This is usually one of the largest swings between projects.
  • Access, Drainage and Plumbing
    • Difficult access, such as working through the house, increases labour time and site costs.
    • Minor drainage moves may add a few hundred pounds, but relocating a public manhole can add £1,500 or more due to permissions, CCTV surveys and specialist work. Drainage is often the most unpredictable element.
  • Structural Works & Knock-Throughs
    • Structural alterations are typically the single biggest cost swing.
    • Removing an existing door or window without increasing the opening is the most cost-effective option. 
    • Creating a wider 2–3 metre opening usually adds around £2,000–£3,000, including structural calculations and steels.
  • Roof System & Insulation
    • In our projects, the roof system is not a variable cost item. 
    • Every orangery is built with the same fully insulated roof specification to meet current standards and deliver year-round comfort, so this does not change the price up or down.
  • Glazing & External Finishes
    • Specification choices affect manufacturing cost rather than performance.
    • Upgrading frame colours typically adds £500–£700.
    • Moving from French doors to bifold doors can add £1,500 or more, depending on size and configuration.
  • Internal Finishes
    • Including plastering, electrics and heating increases cost but completes the room as a finished space.
    • Stripping these back can reduce the initial budget, but most homeowners choose to include them as they want a turn-key solution.

 

A Real 4 x 3m Orangery Cost Breakdown

Project: Waterlooville

Brief

  • Location: South of England
  • Property type: New-build home
  • Goal: Open-plan orangery with strong garden connection
  • Main concern: Cost control without compromising performance

Specification:

  • Style: Traditional Orangery
  • Roof Type: Flat Roof Lantern
  • Frames: BiFolding Doors + uPVC windows
  • Build: Full Build, Minor internal works

Indicative cost breakdown

  • Base build and walls: £9,689
  • Frames and roof system: £11,934
  • Structural works: £110 (internal door removal)
  • Installation: £4,235
  • Electrics, heating and finishes: £5,576
  • Professional fees and approvals: £2,100

Total (including VAT): £33,644

This sits squarely within the typical range for a well-specified 4 x 3m orangery.

How to Plan Your Own Budget

  • Keeping the rear wall mostly intact helps stay toward the lower end of the range.
  • Standard finishes offer the best balance of cost and performance.
  • Full open-plan layouts and premium glazing push budgets upward.
  • Always allow for making good to existing rooms after knock-throughs.

Common Cost Traps to Avoid

  • Vague quotes without a clear specification
  • Unclear VAT treatment
  • Open‑ended pricing with no cost certainty
  • Ignoring drainage or access constraints
    Forgetting internal making good works

How Precision Handles Pricing

We price orangeries based on clarity, not assumptions.

  • Every proposal includes a written specification in plain English.
  • If it is shown on the drawings and written in the specification, it is included.
  • We provide fixed-price proposals for agreed designs and specifications.

Costs only change if you request additional work or if an issue is uncovered on site that could not reasonably have been identified in advance. In those cases, options are explained and agreed before work continues.

Final Takeaway

A 4 x 3m orangery costs what it does because it is a permanent extension built properly.

Understanding what drives the price lets you control it, budget accurately and avoid surprises.

Orangery vs Extension: Insulation, Comfort & Performance in 2026 – Which is Right for You?

A clear, real-world comparison to help you choose the right year-round space for your home in 2026.

Orangery vs Extension 2026

Read time: 7 minutes

Many homeowners still assume an orangery sits somewhere between a conservatory and an extension – attractive, but not quite as warm or usable.

In reality, a modern orangery is built to the same standards as a flat-roof extension.
Same foundations. Same walls. Same year-round performance.

The Short Answer

  • Structure & insulation
    • Both are permanent extensions: proper foundations, insulated cavity walls. No inherent performance gap if designed correctly.
  • Comfort & heating costs
    • A modern orangery should be just as warm in winter and comfortable in summer as a flat‑roof extension. There is no ongoing “penalty” on your heating bill for choosing an orangery.
  • Natural light & feel
    • Orangeries usually bring in more controlled natural light via roof lanterns and carefully positioned glazing, creating a brighter, more “feature” space than a fully solid‑roof extension.
  • Cost to build
    • Orangeries are often slightly more cost‑effective because of prefabricated roof systems that reduce time on site. Not because the standards are lower.
  • Planning & Building Regulations
    • Both follow the same rules. An orangery does not get treated more leniently or more strictly by planning; it’s simply another form of extension. The benefit of a Orangery is that is does not always require building regulations.
  • Resale & value
    • When built correctly, both are treated as permanent, habitable extensions by buyers and surveyors. An orangery can feel more desirable because of the extra light and design detail.

The real decision is about style and light. Not whether it’s a “proper” room.

The Biggest Myth we hear about orangeries

“An orangery won’t be as insulated as a proper extension.”

This is one of the most common misconceptions we hear — and it usually comes from confusing older, traditional orangeries (or conservatories) with modern builds.

The reality

A modern orangery is an extension.

It is:

  • Built on proper foundations
  • Constructed with insulated cavity walls
  • Designed to meet Building Regulations
  • Finished as a permanent, habitable room

It is not an upgraded conservatory.

The term orangery describes the architectural style, not the performance level.

Structure: Why an Orangery Is Built Like an Extension

Brickwork & Walls

One of the biggest reasons an orangery performs like an extension is the amount of solid construction.

Compared to a conservatory, an orangery typically includes:

  • Substantial brick or block walls
  • Insulated cavity construction
  • Reduced full-height glazing

This improves:

  • Thermal efficiency
  • Acoustic comfort
  • Structural solidity
  • The “permanent” feel of the space

Visually, it removes the glass-box look and makes the room feel fully integrated with the house.

Key point:
An orangery is not “similar to” an extension — it is one, just designed with more architectural detail.

Real-world example:
On this project, the orangery was designed and built as a full extension. With insulated cavity walls, permanent foundations and a solid roof. It seamlessly integrates into the existing kitchen-lounge.

The result wasn’t a “garden room” or seasonal space, but a permanent, year-round living area that performs exactly like a traditional extension.

Corner Pillars (Why They Matter)

Corner pillars are a defining orangery feature — and they’re not just aesthetic.

They:

  • Break up large glazed elevations
  • Reduce heat loss compared to full glass corners
  • Add a solid, permanent feel
  • Provide fixing points for external lighting
  • Improve proportions and symmetry
  • In some cases, add structural stability

This is a small design detail that makes a big difference in how the space feels day to day.

Roof Performance: Where Year-Round Use Is Won or Lost

If there’s one element that determines whether a space is genuinely usable all year, it’s the roof.

Modern orangeries use fully insulated flat roof systems, not lightweight glazed or hybrid solutions.

What actually matters to homeowners

  • Permanent structure
  • Strong thermal performance
  • No condensation risk
  • Comfortable in winter and summer
  • Built to Building Regulations (if required)

Modern prefabricated roof systems deliver all of this. Often outperforming many traditional flat roofs.

Insulation (Simplified)

Rather than focusing on technical jargon, here’s what matters:

  • Over 200mm of insulation (thicker than most standard systems)
  • Designed and tested to achieve excellent thermal performance
  • Keeps heat in during winter
  • Prevents overheating in summer
  • Designed to avoid condensation and moisture build-up

This is why modern orangeries are genuinely year-round living spaces, not “three-season rooms”.

Real-world example:
On this project, the orangery was constructed with a fully insulated flat roof designed for permanent, everyday use.

The space now functions as part of the main home all year. Not a seasonal room. This reinforces that modern orangeries deliver the same comfort and thermal performance as a traditional extension.

👉 View the Case Study here

Cost: Is an Orangery Cheaper Than an Extension?

Often, yes – even though it’s built to the same standard.

Why orangeries can be more cost-effective

The difference comes down to construction method, not quality.

  • Orangery roofs are typically prefabricated
  • Manufactured in controlled conditions
  • Assembled quickly on site
  • Reduce labour time and disruption

This saves on:

  • Installation time
  • Labour costs
  • Site disruption

Important reassurance

This does not affect:

  • Insulation
  • Structural performance
  • Longevity
  • Appearance
  • Comfort

Prefabrication is increasingly standard across UK construction because it improves consistency and efficiency. Not because it’s lower quality.

Heating costs

When built correctly, an orangery:

  • Is insulated to the same standards as a flat-roof extension
  • Has no higher heating costs
  • Performs just as efficiently

There is no ongoing “penalty” for choosing an orangery.

Light, Doors & Openings: Will it feel Bright Enough?

This concern comes up frequently – and almost never reflects reality.

There’s no single statistic that measures how a room feels, but real-world feedback matters.

What we see in practice

Across orangery projects:

  • Feedback is never about lack of light
  • Spaces are consistently described as bright, open and balanced

In fact, when designing traditional tiled extensions, we often raise the risk of reduced daylight due to fully solid roofs.

With orangeries:

  • Glazing is designed in deliberately
  • Roof lanterns or glazed panels are proportioned carefully
  • Light is drawn deeper into the room

If you look through our Orangery projects you’ll see the same result: light-filled spaces that still feel solid and comfortable.

Bi-Fold Doors & Structure: No Chunky Steel Required

For homeowners wanting wide openings, structure matters.

Modern orangery systems are engineered to:

  • Span large openings
  • Use integrated structural solutions
  • Avoid bulky RSJs where possible

This results in:

  • Cleaner ceilings
  • Better proportions
  • Reduced structural disruption
  • Lower additional costs

Real-world example:
This orangery demonstrates how large bifold openings can be achieved without compromising comfort or performance.

Despite wide spans and open sightlines to the garden, the orangery remains warm in winter and cool in summer. This is because the structure, roof and walls are built as a complete extension, not a glazed add-on.

Integrated Structure & Open-Plan Living: Removing the Boundary Between Inside and Out

One of the biggest advantages of choosing an orangery over a conservatory is the ability to properly open up the back of the house.

This is where an orangery truly behaves like an extension — not just visually, but structurally.

Removing Walls, Doors & Windows

Because a modern orangery is built as a permanent extension, it allows you to:

  • Remove existing rear walls
  • Take out old doors or windows
  • Create a fully open-plan connection between house and new space

This transforms the orangery from a “separate room” into a true continuation of the home. Often becoming part of the main kitchen, dining or living area.

You simply can’t achieve this safely or compliantly with lightweight or seasonal structures.

How This Is Made Safe (And Why It Matters)

When internal walls are removed, the structure of the house must be properly supported.

That typically involves:

  • Structural steel (or engineered alternatives)
  • Structural calculations by an engineer
  • Building Regulations approval
  • Inspection and sign-off

This isn’t optional – it’s what ensures:

  • The existing house remains fully supported
  • Loads are transferred correctly
  • The space is safe long term

An orangery is designed with this in mind from the outset, which is why it supports large internal openings without compromise.

Does This Affect Cost? (Honest Answer)

Yes – opening up the house does increase cost, and it’s important to be upfront about that.

Additional costs can include:

  • Structural steel or engineered supports
  • Structural engineer calculations
  • Building Regulations design and inspections
  • Additional labour and temporary supports

However, these costs are not orangery-specific.

They apply to:

  • Any extension
  • Any internal wall knock through

In other words, this isn’t a downside of choosing an orangery. It’s simply the cost of creating a proper open-plan extension.

Why Orangeries Are Particularly Well-Suited to Open-Plan Design

Orangeries work especially well in open-plan layouts because they combine:

  • Solid structure (like an extension)
  • Carefully controlled glazing
  • Strong roof performance

This avoids the common problem of:

  • Large open spaces that feel cold
  • Glare-heavy rooms
  • Structurally awkward transitions

Real-world example:
Projects like this one show how wide internal openings and large external bifolds can be combined into a single, cohesive living space. One that works year-round. Not just in summer.

Regulations & Resale: How are Orangeries treated Long Term?

Planning Permission: Are Orangeries Treated Differently?

No.

An orangery follows exactly the same planning rules as any other extension.

  • Same Permitted Development limits
  • Same height, depth and boundary rules
  • Same considerations for listed buildings, conservation areas and new-build estates

The product type does not determine planning — the rules do.

If you want the full breakdown, we cover it here:
👉 Do I Need Planning Permission in 2026? A Simple Homeowner Guide

Building Regulations: Reassurance, Not a Barrier

Building Regulations are often seen as a hurdle — but in reality, they exist to protect you.

What matters to homeowners

  • Will it pass?
  • Will it delay the build?
  • Will it cause stress?

Modern orangery systems are:

  • Independently tested and certified
  • Designed to meet Building Regulations
  • Approved through recognised inspection routes

The process is predictable, smooth, and repeatable — not experimental or risky.

Building Regulations shouldn’t be something to fear.
They should be reassurance that your space is built properly.

Resale Value: How Are Orangeries Viewed by Buyers?

There’s no separate category for “orangery value” — because when built correctly, orangeries are treated the same as extensions.

They are considered:

  • Permanent
  • Habitable
  • Year-round living space

Where orangeries often go one step further is desirability.

In a like-for-like comparison between two similar homes:

  • Same location
  • Same layout
  • Same size

The home with an orangery often feels more appealing due to:

  • Increased usable floor space
  • Better natural light
  • More flexible living

That differentiation can influence both value and speed of sale.

Roof-Only Conversions: A Popular Alternative

For many homeowners, a roof-only conversion is a smart option.

Why people choose this route

  • Retains existing frames
  • Preserves light
  • Delivers full year-round usability
  • Faster than a rebuild
  • More cost-effective

Structural reality

  • Modern roof systems are lighter than glass roofs
  • Existing foundations are often suitable
  • Frames are checked and reinforced if required
  • Footings are assessed before installation

Final Takeaway

A modern orangery is a flat-roof extension with architectural glazing. Not a compromise between a conservatory and an extension.

You get:

  • The insulation and comfort of an extension
  • The permanence and compliance of an extension
  • With more light and refined design

Choosing an orangery is not choosing a second-best option.
It’s choosing a different style of extension.

Do I Need Planning Permission in 2026? A Simple Homeowner Guide

Most single-storey extensions in 2026 won’t need full planning permission But certain sizes, heights and locations still do. Here’s the simple guide to know which applies to your project.

Read time: 7 minutes

in 2026 will I need planning permission for my extension Project?

Short answer: Most single-storey extensions in 2026 do not require full planning permission – as long as they meet the UK’s Permitted Development (PD) rules. But if your design is too large, too tall, in a restricted area, or connects to an older extension, you may need Prior Approval or Full Planning Permission instead.

This guide lays out the rules simply. It includes real homeowner scenarios, so you’ll know where you stand before starting your project.

1. First: How Planning Permission Actually Works in 2026

Before we dive into the rules, let’s break down the three types of permissions in the UK.

A) Permitted Development (PD)

✔ No full planning required

✔ Fastest, simplest route

✔ Works for most single-storey extensions

✔ Still requires Building Regulations

PD is what most customers use their projects.

If you stay within PD limits, you skip the planning process entirely.

B) Prior Approval (Larger Home Extension Scheme)

A halfway step between PD and full planning.

✔ Needed only when depth is:

  • 6m on semis/terraces

  • 8m on detached

The council checks impact on neighbours but the process is much lighter than full planning.

C) Full Planning Permission

Required when:

  • You exceed PD limits.

  • You live in a conservation area / AONB / listed building.

  • PD rights are removed (common on new-build estates)

  • You want a more complex or taller design.

  • You link onto an existing extension and exceed the limits.

This is the slowest route – but sometimes is essential.

2. The Permitted Development Rules Explained (Simple + Visual)

These are the rules most homeowners fall under.

✔ How far you can extend (projection depth)

  • Detached home: up to 8m (via Prior Approval)

  • Semi-detached / terrace: up to 6m

Without Prior Approval:

  • Detached = 4m

  • Semi/terrace = 3m

Important detail most people miss:

Projection is always measured from the “original rear wall” of the house — not the current one.

This means:

  • Bay windows count as part of the “original” wall.

  • Previous extensions push the measurement forward.

  • L-shaped houses measure from the furthest rear point.

This detail changes everything for some projects.

If the back of your house isn’t in a straight line and has “steps,” each step counts as part of the original rear wall.
This means you measure your extension from the part you are building from, as long as none of the new walls go beyond the permitted depth.

In the example below a semi-detached house can extend 3m from the original rear wall.

✔ Height rules (simple version)

  • Max eaves height: 3m if within 2m of a boundary

What “Eaves Height” Actually Means (Clear Definition)

To avoid confusion, here’s the exact definition:

The eaves are the point where the wall of your extension meets the lowest part of the roof.

In even simpler terms:

👉 Eaves height = the height of the wall before the roof begins.

  • Max overall height:

    • 4m (dual pitch)

    • 3m (flat roof)

  • Cannot be taller than your house

The same approach is taken for flat roofs.

✔ Width and placement

  • You can’t extend beyond half the width of the original house

  • You cannot extend forward of the main elevation.

✔ Roof types allowed under PD

All of these can be PD:

  • Glass roof = Conservatory

  • Flat roof = Orangery

  • Tiled roof = Extension

As long as the design stays within the PD limitations.

✔ Materials

Must be “similar in appearance” to the main house.

We achieve this with:

  • Matching brickwork

  • Matching render

  • Same colour schemes

  • Heritage detailing

This is why Precision designs look “natural” – and why they often fall comfortably under PD.

3. When You NEED Full Planning Permission

Full planning is required if:

  • You live in a conservation area.

  • Your home is listed.

  • PD rights have been removed (common on estates built after 2010).

  • Your design is too deep or too tall.

  • You want to build on the side or front.

  • Roof height exceeds PD.

  • You’re creating a balcony or raised platform.

  • You connect your new extension to an existing one and go over the combined limits..

Linking to an older extension often leads to planning issues. The council views the whole structure as one extension.

We take care of this during the design stage, so customers don’t make wrong assumptions.

4. The Most Common Misconceptions (Homeowners Get These Wrong)

This is the section that sets your guide above everyone else’s.

❌ 1. “If my neighbour objects, my project will be refused.”

False.

A neighbour objection only matters if it raises a valid planning concern, such as:

  • Loss of light

  • Overlooking

  • Overshadowing

“I don’t like it” is NOT a planning reason. Your project can still be approved.

❌ 2. “If I change the design of my conservatory, I need planning.”

Not usually.

Changing:

  • Doors

  • Frame colour

  • Layout

  • Windows

…does not trigger planning as long as the conservatory stays within existing PD limits.

❌ 3. “Changing my conservatory roof always needs planning.”

Not always.

✔ Replacing a glass/poly roof with another?

Usually no planning.

✔ Changing to a tiled roof?

Often PD-compliant as long as:

  • Height doesn’t increase

  • Eaves remain compliant

This is why most tiled-roof upgrades we design do not need planning.

✔ Planning IS needed when the new roof goes outside PD limits.

👉 It’s not the fact that the roof is tiled – it’s whether the new design breaches PD.

✔ Regardless of planning, Building Regulations are ALWAYS required

This applies to every solid roof, because:

  • The structure must support the extra weight

  • A thermal assessment may be needed.

  • Ventilation must comply.

  • Structural calculations are required.

So the simple rule is:

👉 Planning depends on PD limits. Building Regulations are required every time.

❌ 4. “Orangeries need planning but conservatories don’t.”

False. The product type doesn’t matter – only the rules.

A small orangery may be PD. A tall conservatory might need planning.

❌ 5. “You can’t extend a listed building.”

You can – but you need Listed Building Consent.

Councils prefer:

  • Timber

  • Slimline profiles

  • Heritage glass

But in 2025/2026 we are seeing more conservation departments approving aluminium when the design is sympathetic.

❌ 6. “If there was a conservatory here before, I can rebuild without planning.”

Not always.

If the old structure:

  • Exceeded PD.

  • Was built illegally.

  • Was part of a previous extension.

  • Changed the rear elevation layout.

…then you may need planning to replace it.

We check this during survey.

❌ 7. “If it’s PD, I don’t need building regulations.”

Incorrect.

Building Regulations apply to:

  • Tiled roofs.

  • Structural knock-throughs.

PD = removes planning

Building regs = safety & compliance

5. Does Linking to an Existing Extension Require Planning?

Often yes.

Here’s the simple rule:

✔ If your new extension connects to an old extension and the combined depth exceeds PD limits

Planning is needed.

✔ If the old extension already used up your PD rights

Planning is needed.

This is one of the biggest mistakes budget builders make – they ignore this rule entirely.

6. Real-World Scenarios 

Scenario 1 — 4m Orangery on a Semi

✔ PD compliant ✔ No planning ✔ Building regs required

Scenario 2 — 7m Orangery on a Detached Home

✔ Needs Prior Approval ✔ No full planning

Scenario 3 — 4m Orangery on a Detached Home with Internal Wall Removal

✔ PD compliant ✔ No planning ✔ Building regs required

Scenario 4 — Replacing Old Conservatory With Tiled Roof Extension

✔ Often PD if height remains the same ✘ Planning if roof height increases ✔ Building regs required

Scenario 5 — Extension on a New-Build Estate

✘ PD often removed by developer ✔ Planning required ✔ Building regs required

7. Certificate of Lawfulness — Should You Get One?

At Precision, we don’t routinely apply for Certificates of Lawfulness unless:

  • The homeowner requests it.

  • PD limits are tight.

  • Proving legality will help with future sale.

  • The property is in a sensitive area.

It is optional. Not essential. But helpful for peace of mind.

8. How Precision Confirms Whether You Need Planning

We make the planning route clear from the very start so there are no surprises later.

Step 1 — Site Survey

We take accurate measurements. Check boundaries. Assess the existing structure.

Step 2 — Initial Planning Guidance

We explain whether your project is likely to fall under:

  • Permitted Development

  • Prior Approval

  • Full Planning Permission

So you know the route before any design work begins.

Step 3 — PD / Planning Check Before Quoting

Before we quote, we run a full check against PD rules and planning requirements. This ensures your quote is correct and you know what permissions you need.

We will take care of all the permissions for you = remove the hassle.

Step 4 — Structural & Building Reg Design (If Required)

We handle all structural and Building Regulations design as needed. This gives you a specification that’s compliant and ready for your project.

What Makes Active Glass Different – and Why It Changes Everything for Modern Conservatories

Not all glass is created equal. Here’s how modern active glass transforms a conservatory or orangery into year round living space and why your choice of tint matters more than you think.

last updated Nov 12, 2025
category Guides
Share with friends

If you’ve ever stepped into an older conservatory, you’ll know the problem. Boiling hot in summer, freezing cold in winter.

That’s not because conservatories can’t be comfortable. It’s because of the glass.

Modern active glass has completely changed how conservatories, orangeries, and glazed extensions perform. It reflects heat, retains warmth, reduces glare, and even cleans itself. Changing a room that was originally seasonal into a space that functions throughout the year.

Let’s break down what makes it different, and why the right tint can make all the difference.

1. What is Active Glass?

Active glass is high-performance glazing that reacts to the environment around it. A microscopic coating on the glass surface:

  • Reflects solar heat in the summer
  • Retains warmth in winter
  • Reduces glare from direct sunlight
  • Self-cleans using UV light and rainwater

So, while traditional glass simply lets the sun in, active glass manages it. Helping maintain a stable, comfortable temperature all year round.

🌡 Think of it as intelligent glass – it adapts to the weather instead of fighting against it.

2. The Real-World Difference

Most of the heat gain or loss in a conservatory happens through the roof and glazing. That’s why choosing the right glass is far more important than adding extra square footage or fancy features.

💡 Precision Tip: It’s smarter to invest in a high-quality roof system with active glass. This is better than building a bigger structure with cheaper, standard glazing.

Every day, we notice homeowners who focus on size or extras. They often get a beautiful space that feels unliveable for half the year.

That’s why most customers choose Active Solar Glass. They want a true home extension, not a pretty but unusable space.

3. Understanding Glass Tints – Which one is Right for you

Different tints don’t only change the look of your roof – they change how it performs.

Here’s how the most common options compare:

🎯 Our Recommendation:

Active Blue remains the standout performer. It provides great heat control, natural light, and visual comfort. That’s why most Precision customers select it for conservatories and orangeries.

 4. Does Active Glass Make the Room Darker?

We know what you might be thinking:

“If the glass is blue tinted does that mean less light or a blue glow inside?”

It’s a great question, and one we hear all the time.

The answer is no – Active Blue and Neutral glass still let in plenty of natural daylight.

They filter harsh sunlight but don’t block brightness.

You’ll see a gentle tone when you look through the glass. Inside, your room stays open, bright, and airy. There’s no glare or “greenhouse” effect like with old polycarbonate roofs.

That balance is about Light Transmission. It measures how much light goes through glass. Too much light can cause glare, making a room uncomfortable. Too little light can make it feel dull. Active Blue glass does it well. It lets in the perfect amount of natural light, creating a bright and comfy space all year.

☀️ In fact, many of our customers comment that their new space actually feels lighter. The glass spreads light evenly in the room. This stops direct sunlight from causing hot spots.

5. Understanding U-Values (In Simple Terms)

You’ll often hear the term U-Value when looking at glass, roofs, and insulation. But what does it mean?

In simple terms:

A U-Value measures how well a material keeps heat in. The lower the U-Value, the better the insulation.

For example:

  • Older glass roofs might have a U-Value around 2.7 W/m²K (lots of heat loss).
  • Modern Active Blue glass is around 1.0–1.2 W/m²K, keeping warmth in during winter.
  • A solid tiled roof can be as low as 0.12 W/m²K – about the same as your house roof.

💡 Think of it like golf – the lower your score, the better.

That’s why the right glass matters. Even if two roofs seem alike, the one with a better U-Value will stay warmer. It will cost less to heat and feel more comfortable throughout the year.

6. The Self-Cleaning Effect

It’s a small detail, but it makes a big difference long term. Plus, most customers do want to spend every weekend cleaning their glass roof.

The outer coating of active glass breaks down dirt using UV light and allows rainwater to wash it away evenly – meaning fewer streaks and less maintenance.

7. Real Proof From our Projects

Every time we install a conservatory or orangery with Active Blue glass, the feedback is consistent:

“It’s warm in winter, cool in summer. We actually use it every day.”

The temperature stability, glare reduction, and light tone make it the top choice for all our customers.

Share with friends

One of the main buying decisions for any homeowner is simple: How do I get the most from my budget

We completely understand. In this industry, it’s no secret that prices can vary wildly. Some quotes are overinflated to cover sales commissions, while others look like a bargain until the work starts. Then quality and service are below your expectations.

That’s why it’s natural to ask: “What should I really expect to pay for a conservatory, orangery or tiled-roof extension in 2025?”

It’s a fair question. And it’s exactly why we created this guide. To give you an honest, up-to-date overview of real project costs, what affects them, and how to make sure your investment delivers genuine long-term value.

Below you’ll find transparent pricing, clear comparisons, and practical examples based on real Precision projects completed across England. 

1. Average 2025 Price Ranges

Build Type

Typical Price Range (2025)

Key Features

Conservatory

£15,000 – £35,000+

Glazed roof, high light levels, cost-effective extra room

Orangery

£25,000 – £60,000+

Brick pillars, roof lantern, premium architectural feel

Tiled-Roof Extension

£25,000 – £60,000+

Fully insulated solid roof, traditional look

2. What Affects the Price

  1. Size & Shape
    • The bigger the footprint, the more glass, roof sections and foundations are required. Larger Simple rectangular builds cost less than angled or complex footprints.
  2. Roof Type
    • Glass roofs are generally cheaper than tiled roofs. Tiled or hybrid roofs provide superior insulation and noise reduction but do cost more.
  3. Colours
    • White Frames: lower cost – will match with any existing house windows.
    • Coloured Frames: 10-20% higher.
      • Precision Tip: Most homeowners split the frame going colour out-white in. This reduces the cost of having a colour. The white inside makes it easier to match the inside furniture. 
  4. Site Access & Groundworks
    • Restricted access, drainage issues or deeper footings increase labour and material costs.
  5. Finishings & Interiors
    • Flooring, plastering, lighting and heating choices can vary a project by several thousand pounds.

3. Cost Breakdown by Example Project

 

3.1 Example 1 – Classic Conservatory (£16-18,000 inc VAT)

  • 4 x 3 m Lean To style with  polycarbonate roof.
  • White uPVC frames.
  • Includes dwarf walls and electrics.

3.2 Example 2 – Modern Orangery (£40-55,000 inc VAT)

  • 3.8 × 5 m brick-based Orangery with aluminium lantern.
  • 2x Anthracite Aluminium BiFolding Doors.
  • Includes planning permission, building regulations, brick pillars, internal house wall removal, plastering and electrics.

3.3 Example 3 – Tiled-Roof Extension (£45-55,000 inc VAT)

  • 7.4 x 3 m solid-roof build with 2x sky vista glass units in the roof.
  • White uPVC frames.
  • Includes building regulations, take-down of the old conservatory,  internal house wall removal, plastering and electrics.

4. How to Keep Costs Under Control

  1.  Design around how you’ll use the space
    • Start with function, not footprint. A slightly smaller, better-insulated build is often more usable and more cost-effective compared to a larger, colder one.
  2. Be realistic about finishes
    •  Interior extras like flooring, lighting and plastering can add 10–20 % to a build. Decide early what’s essential and what can wait. That is how you stay on budget.
  3. Combine materials intelligently
    •  Most Precision builds use aluminium for the doors (for strength and slim-frames) and uPVC for the main frame (for insulation and value). It’s a simple way to achieve a premium look without the full aluminium price tag.
  4. Choose performance over size
    • A high-spec roof and glass package will do more for comfort and resale value than adding an extra half metre in length. Energy efficiency pays you back long after the build.
  5. Fix your price properly
    • Look for a company that offers a fixed-price quote, not an “estimate.” It keeps accountability clear and prevents creeping extras once work starts.

5. What you actually get for your money

Price differences aren’t just about size. They are about specification and finish. Two extensions can look identical on paper but feel completely different once built.

Here is where the money really goes:

Precision Tip: Don’t just compare prices. Compare specification.
A £35,000 conservatory and a £35,000 tiled roof extension deliver very different outcomes in comfort, lifespan, and property value.

6. Which Structure delivers the best value for you?

Each structure has its own strengths. The “best” one depends on how you want to use the space and what look you’re aiming for.

Precision Insight:

If your budget allows, upgrading to an orangery or tiled roof system gives an extra level of insulation and usability all year round.

But don’t overlook a conservatory. With the right roof design, glazing, and heating setup, we can make it a bright, comfortable room that’s functional through every season.

6. Our Honest Summary

It’s easy to get lost in prices, styles, and technical terms — but every successful project comes down to three things:

  1. Clarity at the start — fixed quotes, clear drawings, no assumptions.
  2. Quality materials, chosen for purpose — not upsold for margin.
  3. A company that delivers on its promises.

At Precision, every design is built on those principles.

Whether you choose a conservatory, orangery, or tiled roof extension, our job is to help you invest confidently. We want you to enjoy a finished space that feels like it’s always belonged to your home.

uPVC vs Aluminium – Which Is Better for Your Home?

Trying to decide between aluminium and uPVC? Here’s an honest, real-world look at the pros, cons, and what to think about before spending the extra money.

last updated Oct 27, 2025
category Guides
Share with friends

I met with a customer this week who asked a question we hear all the time:

“Is aluminium really worth the extra money compared with uPVC?”

It is a great question and got me thinking that he, like many homeowners, wasn’t sure what the real difference was beyond the colour or price tag.

So, if you’ve been wondering the same, here’s the simple truth. Both materials are excellent. The right choice depends on how you plan to use the space, what style you want, and how long you expect to stay in the home.

At Precision, we design in both systems, so here’s a transparent comparison to help you choose confidently.

1. Cost & value

In most cases, aluminium frames are around 20–40% more expensive than uPVC equivalents.

That’s because aluminium is stronger, requires more complex manufacturing, and offers slimmer frames.

However, cost isn’t everything.

  • uPVC keeps the project budget lower while delivering great insulation.
  • Aluminium costs more initially but offers a longer lifespan and higher resale appeal thanks to its modern look and build quality. 

💡 Precision Tip: For long-term homes or high-design projects, aluminium is often worth the investment. For classic conservatories or value-led builds, uPVC delivers unbeatable performance for the price.

2. Thermal Performance

Thermal efficiency has levelled out in recent years.

  • uPVC is naturally more insulating, reducing heat transfer through the frame.
  • Aluminium used to lag behind but now features advanced thermal breaks – hidden barriers that stop heat loss.

What is a thermal break?
A thermal break is a thin, non-metal layer (often made of plastic or resin) built inside the aluminium frame.
It separates the cold exterior metal from the warm interior, preventing heat from escaping and condensation from forming.
Think of it like a built-in insulator between the inside and outside of your window or door frame.

When paired with modern active glass or a tiled roof system, both achieve excellent year-round comfort.

Key point: The roof and glazing choice make more difference to warmth than the frame material alone.

3. Strength and Design Possibilities

Because it’s stronger, aluminium allows thinner frames and larger panes of glass without extra supports.

That’s why, on most projects featuring bifold or sliding doors, we’ll specify aluminium for the doors only. This allows the design to handle the size and movement safely and maintain slim sightlines.

The rest of the structure (apart from the roof) can often remain uPVC, keeping costs down and insulation high.

This hybrid approach delivers the best of both worlds: strong, stylish doors with an efficient, budget-friendly frame system.

However, if the goal is a fully contemporary look. Clean lines, minimal frame thickness, and matching colour throughout, then we’ll recommend going fully aluminium for a seamless aesthetic.

Precision Insight: Many customers choose aluminium doors with uPVC frames, but if your design focuses on symmetry or ultra-modern styling, a full aluminium system gives the sharpest finish.

 

4. Maintenance & Lifespan

Both materials are low-maintenance — no painting, no rusting, no warping.

Factor
uPVC
Aluminium
Cleaning Simple wipe-down twice a year Same
Colour fade May dull slightly after 20+ years Powder-coated finish resists fading for 30+ years
Repairs Easy and inexpensive Rarely required

Real-world view: We expect uPVC systems to last 25+ years and aluminium around 35+ years, depending on location and care.

 

5. Style & Colour Options

Both offer extensive customisation:

  • Unlimited RAL colours on both aluminium and uPVC.

  • uPVC can also achieve realistic woodgrain effects. Rosewood, Golden Oak, Irish Oak, and more.

  • Aluminium provides a flawless, contemporary finish but cannot replicate woodgrain texture.

So, if you’re trying to match existing Rosewood windows, uPVC is ideal. If you’re after clean anthracite lines or dual-tone contrast, aluminium will look sharper.

5. Sustainability

Aluminium is one of the most recyclable materials on earth. It can be reused indefinitely without losing quality.

uPVC is also recyclable, though it slightly downgrades each time it’s reused.

Both materials are eco-friendly options when sourced responsibly and installed with energy-efficient glazing.

5. Quick Summary

Priority
Best Choice
Lower cost uPVC
Sleek, modern design Aluminium
Woodgrain / heritage look uPVC
Large openings (bifolds/sliders) Aluminium
Long lifespan Aluminium
Energy efficiency Both (depends on roof/glass)

Our Honest View

Every home and every homeowner is different. 

Aluminium offers strength, sharp lines, and a longer lifespan. uPVC offers warmth, flexibility, and the option to match existing finishes.

At Precision, we design in both materials because the best system is the one that fits your space, budget, and style not a one-size-fits-all answer.

Sauna in Summer, Icebox in Winter? Here’s How We Fix the Conservatory Problem

Say goodbye to extreme temperatures—discover the smart upgrades that turn your conservatory into a comfortable, year-round living space.

last updated Sep 3, 2025

Share with friends

We’ve all heard the joke… Conservatories are either boiling hot in summer or freezing cold in winter.

And honestly? Older builds earned that reputation. They had thin polycarbonate roofs, poor ventilation, and no insulation. But modern conservatories? They have come a long way.

Here’s how we tackle the usual conservatory temperature problem to ensure yours stays comfortable all year long:

1. Upgrade the Roof

The roof is the biggest game changer. We offer options like:

  • Tiled insulated roofs – create a solid extension feel, with fantastic thermal performance.
  • Hybrid roofs – a mix of solid panels and glazing to let in light without the heat.
  • High-performance glass roofs – with solar control, heat reflection, and noise reduction.

You don’t need to choose between light and comfort anymore—you can have both.

2. Use Active Glass

Forget the old greenhouse effect. Our active glazing reflects heat away in summer and retains warmth in winter. Bonus: It also cuts glare and helps keep the glass clean by breaking down dirt and debris. This is especially useful near trees or if birds visit often.

3. Insulate and Ventilate

Good insulation is key—not just in the roof, but in the base, walls, and frames. And just as important? Proper ventilation. Opening vents, trickle vents, and even a small roof vent can make a huge difference to airflow and comfort.

 

4. Choose Quality Frames and Doors

Cheap uPVC frames can let draughts in and heat out. We use high quality, energy-saving frames and doors. They keep your conservatory snug and at a steady temperature. So, you won’t shiver in winter or sweat by mid-morning.

 

5. Think Ahead with Heating and cooling

Plan for comfort, not just structure. Options like:

  • Underfloor heating
  • Slimline radiators
  • Ceiling fans or smart blinds …can help you control the environment year-round.

The result? A room you can actually use—every single day of the year.

Whether you’re using it as a kitchen extension, playroom, garden lounge or even a home office, a properly built conservatory adds space and value—without becoming a seasonal regret.

Which One Wins? The Truth About Conservatories and Orangeries

They might look similar at first glance, but conservatories and orangeries offer very different styles, structures, and benefits. Here’s what sets them apart and how to choose the right one for your home.

One of the most common questions we get asked is, “Should I choose a conservatory or an orangery?””

Both add space, light, and value to your home. But they have different builds, feel different, and suit different needs. Let’s break it down.

What is a Conservatory?

A conservatory is a fully glazed structure, typically with:

  • Large glass walls on all sides
  • A glass roof (or more recently, a hybrid or tiled roof)
  • A lighter, brighter feel with garden views all around

Conservatories are designed to bring the outside in. They bring in plenty of natural light. They are great if you want a room that feels linked to your garden.

What is an Orangery?

An orangery is a sturdy, room-like structure. It mixes classic extension features with big windows and a central roof lantern. It typically includes:

  • Solid pillars or brickwork walls (often 50%+ of the structure)
  • A flat roof with a central glazed lantern
  • More insulation and a cosier feel

Orangeries feel more like a seamless continuation of your home. They are ideal for kitchens, dining rooms, or lounges that need a balance of light and structure.

Main differences at a Glance

Feature
Conservatory
Orangery
Wall Structure Mostly glass Solid walls with glass inserts
Roof Often fully glazed or hybrid Flat roof with central lantern
Appearance Bright, airy, garden-facing Elegant, architectural, extension-style
Feel Light-filled and open Cosy, solid, room-like
Best for Garden rooms, lounges Kitchens, dining areas, year-round use

 

Which one should you choose?

The right choice depends on:

  • How you’ll use the space — e.g., daily family use vs. occasional lounging
  • How much light you want vs. insulation
  • The style of your home — traditional vs. modern, detached vs. semi
  • Your budget and timeline

Need lots of light and a garden connection? A conservatory could be perfect. Want something more substantial, with that “extension feel”? An orangery might be the better fit.

 

Or have the best of both

Thanks to modern materials and clever design, you can now mix features from both:

  • Glazed walls with insulated pelmets
  • Solid base walls with large doors
  • Roofs that combine tiled sections and roof lights

We’ll help you design a space that looks and feels exactly how you want it — without needing to squeeze into one label.
