Covering Leatherhead
We work in Leatherhead (KT22) and the places around it, including Epsom, Ewell and Esher.
Homes in the South East
Housing across the South East mixes inter-war semis, post-war estates and older cottages in villages and market towns, so rear and side extensions, hip-to-gable lofts and garage conversions all come up regularly.
What does a garage conversion involve?
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.
- Building control application
- Insulated floor, walls and ceiling
- Heating, electrics and data points
What will a garage conversion cost?
Typical ranges for garage conversions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.
| Garage conversions | Guide price incl. VAT |
|---|---|
| Single integral garage | £12,000 to £17,000 |
| Single attached garage | £12,000 to £24,000 |
| Single detached garage | £18,000 to £30,000 |
| Double garage | £25,000 to £54,000 |
Do you need permission for a garage conversion in Leatherhead?
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. We check the original permission for your house.
What can change the price or programme?
- Some new-build estates have a planning condition keeping garages for parking.
- Losing a parking space can matter on streets with permit parking.
