What does a garage conversion involve?
A garage conversion turns an attached, integral or detached garage into a habitable room by infilling the door opening, insulating the floor, walls and roof, and adding windows, heating and power. It is one of the quickest and cheapest ways to add a room.
- Planning check (some estates remove permitted development rights)
- Garage door removal and brick infill with window
- Heating, electrics and data points

Planning and building rules in Swansea
Planning decisions in Wales are made by the local council, using permitted development rules set by the Welsh Government rather than England’s. Building regulations in Wales have their own approved documents, and the Party Wall etc. Act 1996 applies to work on shared walls and boundaries.
In Wales, converting an attached garage usually does not need planning permission unless rights have been removed by condition or the building is listed.
What can change the price or programme?
- The garage floor is often lower than the house and needs raising.
- A bedroom needs an escape window or a protected route out.
