Covering Finchley
Our coverage around Finchley (N3) also includes Muswell Hill (2 miles to the east) and Cricklewood.
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 included in a garage conversion in Finchley?
Most integral garages already have the walls and roof; what they need is a new insulated floor, an infilled front wall with a window, and heating. We check whether your permitted development rights are intact, handle building control and finish the room ready to use.
- Building control application
- Heating, electrics and data points
- Plastering, skirting and decoration-ready finish
How much should I budget for a garage conversion?

|---|---|
| Single integral garage | £12,000 to £17,000 |
| Single attached garage | £12,000 to £24,000 |

| Double garage | £25,000 to £54,000 |
How is a garage conversion approved in Finchley?
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.
An internal garage conversion is usually permitted development in England unless the house is listed, an Article 4 direction applies, or it is on an estate where the planning permission removed permitted development rights.
What should Finchley homeowners check first?
- Some new-build estates have a planning condition keeping garages for parking.
- A bedroom needs an escape window or a protected route out.
From first call to completion
- 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.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
