Frequently asked questions
Do I need planning permission for a garage conversion?
Most internal garage conversions are permitted development and do not require planning permission. You will need Building Regulations approval. If you are altering the external appearance significantly, live in a listed building or a conservation area, or the garage was built as a condition of a planning permission, you may need consent.
How much does a garage conversion cost?
A basic single garage conversion to a habitable room costs £8,000–£15,000. Adding a bathroom or en-suite adds £3,000–£6,000. A full-quality conversion with insulation, plastering, electrics, heating, floor screed and new door/window openings typically runs £12,000–£25,000.
Does a garage conversion add value?
Converting a single garage into a habitable room typically adds 10–15% to a property's value, more in urban areas where extra bedrooms are premium. The value increase often exceeds the conversion cost. Note that losing off-street parking can marginally reduce value in some areas — a surveyor can advise.
Can any garage be converted?
Most integral (attached) garages and many detached garages can be converted. Key considerations: floor level (must be raised to habitable standard), damp-proof course, insulation standard for walls/roof, and structural integrity of the existing structure. A builder will survey and advise before quoting.
How long does a garage conversion take?
A straightforward single garage conversion takes 3–6 weeks. Adding a bathroom or making structural changes extends this to 6–10 weeks. Building Regulations inspections during the work add time — factor this into your schedule.
Do I need to tell my mortgage lender or insurer about a garage conversion?
Yes. You should inform your home insurer (the property description and rebuild cost change) and check with your mortgage lender whether their consent is required. Failure to notify your insurer can invalidate your cover.
