Homes in the East of England
Housing in the East of England ranges from post-war estates and modern developments to timber-framed and period homes in historic towns, so permitted development checks and conservation controls both feature regularly.
What is included in a garage conversion in St Albans?
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
What will a garage conversion cost?
Use these ranges to budget for garage conversions; the survey turns them into a fixed price for the agreed specification.

| Single attached garage | £12,000 to £24,000 |

How is a garage conversion approved in St Albans?
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 can affect a garage conversion?
- The garage floor is often lower than the house and needs raising.
- Losing a parking space can matter on streets with permit parking.
