What we do
How we help — Garage Conversions
Integral garage conversions
The most common case — converting a garage built into the house into a warm, usable room.
Detached garages
Where a separate garage becomes an office or studio, with its own considerations.
Insulation, damp & floor levels
The technical essentials that turn a cold garage into a comfortable, compliant room.
Fire separation
Detailing where the converted space adjoins the rest of the house.

Read case studyPlanning permission route
Converting a garage within the existing structure is often permitted development, particularly where the external appearance changes little. However, replacing the garage door with a window or wall changes the frontage, and some areas have conditions (or Article 4 directions) that remove these rights.
We advise on the likely route and, where useful, prepare drawings for a Lawful Development Certificate — subject to confirmation with your local authority.
Building regulations route
Garage conversions need building-regulations approval. The key areas are insulation and damp-proofing, raising and insulating the floor, ventilation, and fire separation where the garage adjoins the house.
We prepare the drawings and specifications that building control needs.

Questions
Garage Conversions — common questions
Often it's permitted development if it stays within the existing structure, but changing the frontage or an Article 4 area can change that. We advise on the likely route, confirmed with your local authority.
Yes — insulation, damp, floor levels, ventilation and fire separation all fall under building regulations. We prepare those drawings.
Often yes — a partial conversion keeping storage at the front is a popular approach, and we can design for it.
