Planning and approvals in Plumstead
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 Plumstead address depends on its history and any designations, which is why we check it at the first visit.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
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).
Who an orangery extension suits
- Homeowners replacing an older conservatory
- Period and detached houses with a garden view
- Those who want daylight without overheating
Covering Plumstead
Our survey diary covers Plumstead, including DA16, SE2, SE18, SE28. Nearby, we also take on projects in Abbey Wood (1 mile), Welling (2 miles), Thamesmead (2 miles), Eltham (3 miles).
For homes towards Kent, Dartford is around 6 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.

How the project works
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
Drawings are prepared and agreed with you, then submitted for the right planning route and building regulations approval.
Fixed written price
With the design and specification agreed, you get a fixed written price and a start date.
Build and sign-off
The build is managed from start to finish, inspected at each stage and signed off on completion.
Your questions about an orangery extension in Plumstead
Do you cover all of Plumstead?
Yes. We cover Plumstead and the surrounding parts of Greater London. Site visits are free and there is no obligation.
Who do I contract with for an orangery extension in Plumstead?
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 Plumstead?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
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.
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 Plumstead.
