Double garage to annexe for my father-in-law. Total cost £28k including kitchenette and shower room. The builder via BestBuilders sorted everything from drawings to final inspection. Fantastic outcome, would recommend.

Converted our garage into a playroom for the kids. Initially worried about damp from the existing slab but our specialist did proper damp-proofing and full insulation upgrade. Came in on budget at £11k. Two minor snags fixed within a week.
