Orangery extensions across Norbury

- PlanningSame limits as single-storey rear; glazing checked for building regs
- Build time10–16 weeks on site

What is included
- Design of piers, roof perimeter and lantern proportions
- Heating sized for the glass area
- Thermal calculations where glazing is generous
- Foundations, walls and insulated perimeter roof
- Opening into the main house
- Aluminium or timber lantern and full-height glazing
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 Norbury
We cover Norbury and the postcode districts CR7, SE19, SE27, SW16. Neighbouring towns we cover include Upper Norwood (1 mile), Streatham (1 mile), Tooting (2 miles), South Norwood (2 miles).
Just over the Surrey border, Ewell is about 7 miles away. London's housing is dominated by Victorian and Edwardian terraces, many with a rear outrigger and a side return, and 1930s semis in the outer boroughs. Conservation areas are common, so the planning check comes first.
Will the council need to approve it?
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.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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).

Questions people ask about orangery extensions
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Norbury, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do I need building regulations approval in Norbury?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
How long does an orangery extension take to build in Norbury?
On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.
How much does an orangery cost?
Our guide range is about £3,120 to £5,850 per m² including VAT, so a 16 m² standard-spec orangery is typically £58,000 to £73,000 in Norbury.
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.
