Covering Banstead
Banstead is about 17 miles east of Guildford. We also cover Sutton (2 miles to the north), Ewell and Epsom.
Homes in the South East
The South East has a lot of 1930s and post-war semi-detached housing, well suited to rear extensions and hip-to-gable loft conversions, alongside period properties in conservation areas that need a more careful design.
What goes into 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.
- Planning check (some estates remove permitted development rights)
- Insulated floor, walls and ceiling
- Heating, electrics and data points

Do you need permission for a garage conversion in Banstead?
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.
