Garage conversions in Surrey
Surrey Build Group converts and renovates garages across Surrey, turning underused space into home offices, bedrooms, playrooms and annexes. We handle the design, building control and full build, from insulation and new floors to the finished room.
Overview
How we deliver garage conversions
Most integral and attached garages convert well. We replace the garage door with a window and wall that match the house, insulate the floor, walls and roof, add heating and electrics, and finish the space so it feels like part of the original home.
We also renovate detached garages and outbuildings. One recent project gave a detached garage cream horizontal cladding, a dark roller shutter door, a tiled roof with Velux windows and stained glass in the gable end.

Questions
Garage conversions: your questions answered
Do I need planning permission to convert my garage?
Converting an integral or attached garage is often permitted development, especially where the work is internal. Some newer estates have conditions that remove permitted development rights, and homes in conservation areas may need consent. We check the planning history of your property before we start.
Does a garage conversion need building regulations approval?
Yes. Turning a garage into a habitable room needs building regulations approval, covering foundations, insulation, ventilation, fire safety and moisture protection. We manage the application and inspections.
Can a garage become a bedroom or a home office?
Yes. A converted garage makes an excellent home office, guest bedroom, playroom or gym. We design the room around how you plan to use it, including heating, lighting, power and storage.
