Convert a Garage Into a Bedroom

It may be possible, subject to the condition and size of the garage and the proposed layout. Survey the usable space after insulation and finishes, and consider access, ventilation, heating, damp protection and fire safety as part of the design.

Our starting guides are £11,000 for a partial conversion and £14,000 for a full single conversion. The written quotation depends on the building, intended use, services and finish. A bathroom or bespoke features must be assessed and priced for the project rather than assumed to be included.

There is no guaranteed increase. The effect depends on the property, room quality, approvals, local demand and any lost parking or storage. Ask a local surveyor or valuer how they would assess your proposed layout and keep the relevant completion documents.

The design needs appropriate ventilation and fire-safety arrangements for the room and its relationship to the house. Position windows with the furniture layout and daylight in mind; the precise technical requirements and escape arrangements should be confirmed through the building-control process.

Possibly. Check that the room remains practical once a bathroom is added and that drainage, water supply and ventilation routes are feasible. Specify the fittings and finishes and obtain a project-specific price.

Converting a garage, including only part of it, into living accommodation normally requires building-regulations approval. This is separate from planning permission. Before work starts, agree the approval route, who makes the application, the inspection stages and who pays the fees. Any application support provided by JB is set out in the quotation; required approval is not an optional upgrade.

Planning permission is not usually needed for internal garage-conversion work that does not enlarge the building, but property-specific restrictions can change that. Check existing planning conditions, limits on permitted development and listed-building requirements. A proposal for a separate dwelling needs particular advice from the local planning authority.
