What do you get with a garage conversion?
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.
- Building warrant application and completion certificate
- Garage door removal and brick infill with window
- Plastering, skirting and decoration-ready finish
How much should I budget for a garage conversion?

Do you need permission for a garage conversion in Grangemouth?
Projects in Scotland need a building warrant from the council before any building work starts, and a completion certificate once it is finished. Planning permission is a separate decision. The Party Wall etc. Act does not apply in Scotland; shared walls are governed by title deeds and the law of the tenement where relevant.
In Scotland, converting a garage may not need planning permission if the outside barely changes, but a building warrant is needed before work starts.
What should Grangemouth homeowners check first?
- The garage floor is often lower than the house and needs raising.
- A bedroom needs an escape window or a protected route out.
What happens after I enquire?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
