Covering Tonbridge
Tonbridge sits 12 miles south-west of Maidstone, with Tunbridge Wells 4 miles to the south and Sevenoaks 6 miles to the north-west.
Homes in the South East
Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.
What does a garage conversion involve?
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
- Garage door removal and brick infill with window
- Insulated floor, walls and ceiling

How is a garage conversion approved in Tonbridge?
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 I think about before starting?
- Some new-build estates have a planning condition keeping garages for parking.
- Losing a parking space can matter on streets with permit parking.
