Covering Thetford
Alongside Thetford, we also cover Bury St Edmunds, Diss (15 miles to the east) and Swaffham.
Homes in the East of England
Across the East of England, newer estates often have integral garages and room for rear extensions, while older towns have Victorian terraces and conservation areas that shape what can be built.
What goes into 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.
- Insulated floor, walls and ceiling
- Heating, electrics and data points
- Plastering, skirting and decoration-ready finish
How much should I budget for a garage conversion?
Indicative costs for garage conversions. London and the South East usually sit towards the top of each range.
| 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 |
How is a garage conversion approved in Thetford?
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 Thetford homeowners check first?
- Some new-build estates have a planning condition keeping garages for parking.
- The garage floor is often lower than the house and needs raising.
