What affects the price
- Single or double garage.
- Floor level. Most garage floors are lower than the house and need raising.
- Plumbing. Adding an en suite, utility or kitchen means new water and drainage.
- Windows and doors. The new front window, plus any rooflights or doors to the garden.
- Heating. Extending your central heating or adding underfloor heating.
- Finish. Flooring, lighting, built-in storage and decoration.
Does a garage conversion add value?
Usually, because it adds a usable room. In areas where parking is tight, some buyers value a garage or driveway space, so ask a local estate agent if you’re unsure.
Other costs
- Building control fees
- Drawings and structural calculations, if needed
- VAT: check whether your quote includes it
