What is a garage conversion?
A garage conversion turns an integral or attached garage into habitable space, such as a study, playroom, bedroom or utility. The garage door is replaced with a wall and window, the floor is raised and insulated, and the walls and roof are brought up to building regulations.
How much does a garage conversion cost in Stranraer?
In Stranraer, a garage conversion typically costs £17,500–£29,000 for a single integral garage, including VAT at 20% (standard rate). Prices in Scotland sit near the national average for this kind of work, and the range for Stranraer reflects that. Design, structural calculations and council fees are extra.

Do you need planning permission for a garage conversion in Stranraer?
Whether you need planning permission depends on your house and its location in Scotland. In Scotland converting a garage usually does not need planning permission if the outside appearance barely changes, but a building warrant is needed before work starts.
Scotland has no Party Wall Act. Work on shared walls is governed by your title deeds, the Tenements (Scotland) Act 2004 for flats, and common law, so we agree arrangements with neighbours in writing before work starts.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
