Garage conversions in Barnes

We take on garage conversions in Barnes as a complete project: survey, drawings, planning or permitted development checks, building control and the construction itself.

Covering Barnes

Barnes is about 6 miles south-west of London. We also cover Chiswick (1 miles to the north), Putney and Fulham.

Homes in London

Much of London’s housing is Victorian and Edwardian terraces, which is why side return extensions, rear dormers and mansards are so common. Many streets are in conservation areas, and several boroughs use Article 4 directions that remove some permitted development rights.

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.

  • Building control application
  • Insulated floor, walls and ceiling
  • Heating, electrics and data points

Do you need permission for a garage conversion in Barnes?

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 should Barnes homeowners check first?

  • A bedroom needs an escape window or a protected route out.
  • Losing a parking space can matter on streets with permit parking.

How does the project run?

  1. Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
  2. Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
  3. Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
  4. We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
