Garage conversions in March

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

Covering March

Alongside March, we also cover Wisbech, Peterborough (14 miles to the west) and King's Lynn.

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 March?

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.

Single detached garage£18,000 to £30,000
Double garage£25,000 to £54,000

Do you need permission for a garage conversion in March?

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.

What should I think about before starting?

  • The garage floor is often lower than the house and needs raising.
  • A bedroom needs an escape window or a protected route out.

What are the steps?

  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. Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
