Key Building Stages of a Garage Conversion Project

Foundations & Floor Slabs
Inspect the existing foundation for load capacity. Install new floor slab or suspended joists with insulation.

Infilling or Replacing the Garage Door
Replace the door with brickwork or timber, matching the house’s exterior.

Insulating Garage Walls
Add internal insulation to meet energy regulations and ensure comfort.
