Wraparound extensions in Buckinghamshire

Covering Buckinghamshire

Our coverage across Buckinghamshire includes Milton Keynes, High Wycombe, Aylesbury and Bletchley.

Homes in the South East

Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.

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.

How much does a wraparound extension cost in Buckinghamshire?

Wraparound extensions	Guide price incl. VAT

How is a wraparound extension approved in Buckinghamshire?

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. Most need householder planning permission, which usually takes around eight weeks once validated.

What can change the price or programme?

Roof water from an L-shape needs careful falls and outlets.
An open-plan space this size needs a heating plan, often underfloor heating.
