Homes in the East Midlands
The East Midlands combines red-brick terraces in the cities with a lot of post-war and modern estate housing, so rear extensions, garage conversions and loft conversions are all common.
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
- Heating, electrics and data points
How much should I budget for a garage conversion?
Use these ranges to budget for garage conversions; the survey turns them into a fixed price for the agreed specification.

| 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 |
Planning and building rules in Northampton
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.
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.
What are the steps?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
