Covering Greenford
Greenford sits 10 miles west of London, with Northolt 1 miles to the north and Southall 2 miles to the south-west.
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 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.
- Steel frame or goalpost for the corner opening
- Pitched, flat or glazed roof with rooflights
- Optional kitchen supply and installation

Planning and building rules in Greenford
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 Greenford homeowners check first?
- Both neighbours may need party wall notices.
- An open-plan space this size needs a heating plan, often underfloor heating.
What happens after I enquire?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
Wraparound extensions: common questions
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.
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.
