Covering Borehamwood
Borehamwood sits 7 miles south of St Albans, with Barnet 3 miles to the east and Bushey 4 miles to the west.
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 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.
- Planning check (some estates remove permitted development rights)
- Garage door removal and brick infill with window
- Plastering, skirting and decoration-ready finish

How is a garage conversion approved in Borehamwood?
Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 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 change the price or programme?
- The garage floor is often lower than the house and needs raising.
- Losing a parking space can matter on streets with permit parking.
From first call to completion
