Covering Chiswick
Chiswick is about 6 miles west of London. We also cover Acton (1 miles to the north-west), Barnes and Shepherd's Bush.
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 garage conversion?
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.

Planning and building rules in Chiswick
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. We check the original permission for your house.
What should Chiswick homeowners check first?
- The garage floor is often lower than the house and needs raising.
- Losing a parking space can matter on streets with permit parking.
From first call to completion
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- 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.
Does it need building regulations approval?
Yes, because it becomes a habitable room.
