Do I need planning permission in Luton?
In England a glazed or orangery-style extension follows the same size limits as any single-storey rear extension: 3 m or 4 m without an application, or up to 6 m and 8 m through prior approval. Building regulations limit glazing to about a quarter of the new floor area plus the openings it replaces, unless whole-house calculations show the design still performs.
In a conservation area, national park, National Landscape, the Broads or a World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).
What should I budget for an orangery extension in Luton?
Labour and material costs vary across the UK, so for Luton we use our East of England factor (×1.06). The ranges include VAT and exclude design, structural and council fees.

Is an orangery extension right for your house?
- Homeowners replacing an older conservatory
- Period and detached houses with a garden view
- Those who want daylight without overheating
The lantern-to-roof ratio sets the character. A wider solid perimeter gives a calmer, more room-like space and hides downlights and speakers; a bigger lantern feels brighter but needs more care against summer heat.
Extensions in and around Luton
Site visits are available across Luton (LU1, LU2, LU3, LU4, LU5, LU6). Neighbouring towns we cover include Dunstable (5 miles), Leighton Buzzard (11 miles), Ampthill (11 miles), Kempston (17 miles).
Across the East of England many houses sit on generous plots, and single-storey and wraparound extensions are a natural fit.
Our process, step by step
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.
Free site visit
A designer visits, takes measurements and photos, and discusses layouts, budget and timing with you.
Design and approvals
We draw the design, agree it with you and handle planning or permitted development checks and building regulations.
Fixed written price
You receive a written, itemised price and programme. Nothing starts until you are happy with it.
Build and sign-off
The build is managed from start to finish, inspected at each stage and signed off on completion.
Common questions in Luton
How long does an orangery extension take to build in Luton?
On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.
Who do I contract with for an orangery extension in Luton?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Do I need building regulations approval in Luton?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
How much does an orangery cost?
Our guide range is about £2,540 to £4,770 per m² including VAT, so a 16 m² standard-spec orangery is typically £47,000 to £59,500 in Luton.
What is the difference between an orangery and a conservatory?
An orangery has a solid roof perimeter with a central lantern and more solid wall, so it is warmer and more like a room. A conservatory is mostly glass. Building regulations treat a heated orangery joined to the house as an extension.
