Homes in London

Much of London’s housing is Victorian and Edwardian terraces, which is why side return extensions, rear dormers and mansards are so common. Many streets are in conservation areas, and several boroughs use Article 4 directions that remove some permitted development rights.

What is 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.

What approvals does a wraparound extension need in England?

English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.

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.

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.

Wraparound extensions: common questions

Can we keep part of the kitchen working?

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

Glazed roof or solid roof?

A mix usually works best: solid roof with rooflights over the kitchen and a glazed section over the dining area.

Who deals with the council for a project in Dagenham?

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