What moves the price
- Size of the garage — a larger garage needs more insulation, flooring and plasterboard to make it a habitable room.
- Complexity of the design — replacing the garage door with a wall and window, or adding a bathroom, brings in more building work.
- Materials used — the insulation, flooring and finishes chosen for the converted garage drive much of the cost.
- Integral or detached garage — a detached garage needs its own power, heating and insulation run out from the house, which adds cost.
- Need for additional structural changes — raising a low floor or strengthening a roof adds building work before the room can be fitted out.

How to pay less
- Converting the garage into a simple room, such as an office or gym, costs less than adding a bathroom or kitchen.
- Keeping the existing garage walls and roof where they are sound, and insulating inside them, avoids rebuilding costs.
- Doing the painting and decorating yourself after the garage conversion can save on the finishing stage.
- Clearing out the garage completely before the builder starts saves paid time on the first day of the conversion.
- Having the electrics and heating extended during the conversion, rather than later, saves opening up the new walls again.
Before you book
- Access to the garage for assessment and construction work.
- Any design ideas or inspiration you have in mind for the conversion.
- Your budget and timeline for the garage conversion, so the builder can suggest what fits.
- Any existing permits or plans for the garage, which can help show what conversion work is possible.
- You can ask about the builder's qualifications for garage conversions, whether planning permission is needed and how electrics and plumbing will be certified.
