Because you are not building a new structure, you do not ordinarily need planning permission to convert a garage into a room.

However, you may need other types of permission.

Listed building consent

If your home is Grade I or Grade II listed, it is inscribed into law that you must attain listed building consent before making major alterations – and a garage conversion would certainly be classed as a major alteration.

Building regulations approval

The conversion of a garage or part of a garage into a habitable space will require building regulations approval in some form.

The form depends on the type of work involved in the conversion. Here are some examples of work that require approval:

  • Electrics
  • Plumbing
  • Doors and windows
  • Roofs
  • External walls
  • Internal walls and partitions

The good news for you as the homeowner is you do not have to seek building regulations approval yourself. If you hire a professional contractor like us, we will apply for and carry out works to the standards set out in building regulations for you. If necessary, the work is then inspected and approved with a certificate.

The value of your home could also increase with a garage conversion!

Why don’t I need planning permission?

The simple answer is because providing the work is internal and does not involve enlarging the building, garage conversions are classed as permitted development.

This rule applies to houses of all type. Different rules apply to flats, maisonettes and other buildings. Please contact us for advice if these apply to you.

What all this means for getting your garage conversion done

So long as your home is not Listed, and you do not plan on enlarging the building, you can enlist the help of a contractor immediately to convert your garage into a room without applying for planning permission. You do not have to deal with building regs either because your contractor will deal with these for you.
