Wraparound extensions in Cricklewood

Covering Cricklewood

Cricklewood is about 5 miles north-west of London. We also cover Kilburn (1 miles to the east), Willesden and Notting Hill.

Homes in London

London projects often mean working on period terraces with neighbours on both sides, tight access through the house and conservation area controls, so careful planning and party wall work matter as much as the build.

What is a wraparound extension?

Because it removes two external walls, a wraparound needs careful structural design and a good plan for the corner where the steels meet. We design, apply for any permissions, build and finish the shell, and can fit the kitchen as part of the same contract.

How is a wraparound extension approved in Cricklewood?

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 affect a wraparound extension?

The corner steel connection is the critical detail and is designed by a structural engineer.
An open-plan space this size needs a heating plan, often underfloor heating.

Questions about a wraparound extension in Cricklewood

Does a wraparound need planning permission?

Usually yes. In England it combines a side and rear extension, which takes it outside permitted development in most cases.

How long does a wraparound take?

Around 12 to 18 weeks on site after approvals.

Can you visit a house in Cricklewood to quote?

Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
