Local to Bethnal Green
Our survey diary covers Bethnal Green, including E1, E2, E8, EC2A, EC2M, EC3A. Neighbouring towns we cover include Stepney (1 mile), Bow (2 miles), Highbury (2 miles), Stratford (3 miles).
For homes towards Essex, Waltham Abbey is around 11 miles away. In London, space is at a premium and gardens are often short, so side returns, wraparounds and carefully planned rear extensions tend to make the most of every metre.
Planning rules that apply in Bethnal Green
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.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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).

What is included
- Kitchen-led layout planning before the drawings are fixed
- Drainage and services designed for sinks, island and appliances
- Roof lantern or rooflights positioned over the work zones
- Kitchen fitting by our team or coordination with your supplier
We start with the working triangle and the island, then set the doors, glazing and roof lights around it. Getting this order right avoids the classic mistakes: a sink against a blank wall, glare on the hob or a fridge blocking the garden view.

Questions people ask about kitchen extensions

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.

On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 4–12 weeks design and approvals.

Usually under the brightest part of the roof and away from the main walkway to the garden. We test two or three layouts on the plan before deciding.
