Homes in London

Terraced houses dominate many London neighbourhoods, so most projects involve shared walls, narrow access and a party wall process. Conservation areas are widespread, and some boroughs have their own mansard and basement guidance.

What do you get with a wraparound extension?

A wraparound extension combines a side return and a rear extension into one L-shaped build, giving the biggest possible ground-floor space on terraced and semi-detached houses. It usually creates a large open-plan kitchen, dining and living area across the back of the house.

Planning and building rules in Battersea

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.

In England a wraparound extension is treated as one extension, and because it covers both the side and the rear it does not normally fit within permitted development. Most need householder planning permission, which usually takes around eight weeks once validated.

What should I think about before starting?

The corner steel connection is the critical detail and is designed by a structural engineer.
Roof water from an L-shape needs careful falls and outlets.

Often, by sequencing the work so the old back wall comes out last. We agree a plan with you before starting.

We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
