Planning rules that apply in Edmonton
In England a single-storey rear extension can usually go up to 3 m beyond the original rear wall of a semi-detached or terraced house, or 4 m on a detached house, without a planning application, provided it is no more than 4 m high, keeps eaves to 3 m within 2 m of a boundary and, with other buildings, covers no more than half the land around the original house. The larger home extension prior approval scheme raises those depths to 6 m and 8 m, with neighbours notified and a 42-day decision.
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.
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.
Applications are decided by the local planning authority (your district, borough or unitary council).
Local to Edmonton
Our survey diary covers Edmonton, including 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).
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.
What is included
- Roof design matched to the existing pitch and tiles
- Vaulted ceilings or flat ceilings with storage above
- Lead or proprietary flashings to the main wall
- Roof windows positioned for light and ventilation
- Insulation to current building regulations

Your questions about a pitched roof extension in Edmonton
Do I need building regulations approval in Edmonton?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
How long does a pitched roof 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 a pitched roof 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 have a vaulted ceiling?
Yes. A vaulted ceiling with roof windows is one of the main reasons to choose a pitched roof. It needs insulation between and under the rafters to meet the building regulations.
How much does a pitched roof extension cost?
Our guide range is about £2,400 to £4,550 per m² including VAT, a little more than a flat roof because of the roof structure and tiles.
