Do you need planning permission to build a garage?
A detached garage is often permitted development in England if it is single storey, behind the front of the house, with eaves no higher than 2.5 m and an overall height of no more than 4 m (dual-pitched roof) or 3 m (other roofs). Within 2 m of a boundary it must be no more than 2.5 m high. All extensions and outbuildings together must not cover more than half the land around the original house. Listed buildings and designated land have tighter rules, and Wales, Scotland and Northern Ireland differ. A detached garage under 30 m² is often exempt from building regulations, but electrics always need Part P certification.
How this garage build cost calculator works
We multiply the floor area by a 2026 price per m² for the construction type (including a standard base), take about 10% off per m² for double garages, add electrics, an electric door and groundwork if selected, and adjust for your region.
