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 do you get with a garage conversion?
A garage conversion turns an attached, integral or detached garage into a habitable room by infilling the door opening, insulating the floor, walls and roof, and adding windows, heating and power. It is one of the quickest and cheapest ways to add a room.
- Garage door removal and brick infill with window
- Insulated floor, walls and ceiling
- Plastering, skirting and decoration-ready finish

Planning and building rules in Harrow
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.
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 can affect a garage conversion?
- A bedroom needs an escape window or a protected route out.
- Losing a parking space can matter on streets with permit parking.
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.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- 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.
What people ask before starting
Do I need planning permission for a garage conversion?
Usually not if the work is internal and your permitted development rights are intact. Some estates remove those rights, so we check.
How long does a garage conversion take?
About 2 to 5 weeks on site.
Can you visit a house in Harrow 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.
