Edmonton orangery extensions, designed and built
We design and build orangery extensions for houses in Edmonton, with a written price once the survey and design are done and one point of contact throughout.

Planning rules that apply in Edmonton
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.
The planning position for a specific Edmonton address depends on its history and any designations, which is why we check it at the first visit.
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 Edmonton?
Labour and material costs vary across the UK, so for Edmonton we use our London factor (×1.3). The ranges include VAT and exclude design, structural and council fees.
Typical rates in Edmonton: £3,120 to £5,850 per m² including VAT, depending on specification.
| Size | Essential | Standard | Premium |
|---|---|---|---|
| 3 m × 4 m 12 m² | £39,000 – £47,500 | £43,500 – £55,000 | £53,000 – £70,500 |
| 4 m × 4 m 16 m² | £49,500 – £60,500 | £58,000 – £73,000 | £70,500 – £94,000 |
| 4 m × 6 m 24 m² | £74,500 – £90,500 | £87,000 – £109,500 | £106,000 – £140,500 |

Working in Edmonton
Site visits are available across Edmonton (EN1, N9, N13, N17, N18, N21). Neighbouring towns we cover include Ponders End (1 mile), Tottenham (2 miles), Enfield (2 miles), Palmers Green (2 miles).
Just over the Essex border, Waltham Abbey is about 5 miles away. Across London, terraced houses with narrow side returns and tight access are the norm, which shapes everything from party wall notices to how materials reach the back garden.
Included in a typical project
- Aluminium or timber lantern and full-height glazing
- Design of piers, roof perimeter and lantern proportions
- Foundations, walls and insulated perimeter roof
- Thermal calculations where glazing is generous
- Opening into the main house
- Heating sized for the glass area
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.
What happens next
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
First, a site visit: we look at the house, garden, access and drains and listen to what you need.
Design and approvals
We draw the design, agree it with you and handle planning or permitted development checks and building regulations.
Fixed written price
With the design and specification agreed, you get a fixed written price and a start date.
Build and sign-off
We build it with one project manager, book the building control inspections and hand over the completion certificate.
Your questions about an orangery extension in Edmonton
How long does an orangery extension take to build in Edmonton?
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 Edmonton?
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.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Edmonton, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
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.
Will an orangery be too hot in summer?
Not if it is designed with solar-control glass, a solid perimeter and ventilation. We size the lantern and opening vents with that in mind.
