A garage conversion is often the fastest and most affordable way to add a room to your home. Because the structure already exists, costs are typically 30–50% less than building a new extension.
Structural Considerations
- The garage floor usually needs lowering or levelling to match the house floor level
- The existing garage slab may need strengthening or replacing
- Removing the garage door and building a new wall with windows requires a lintel or steel beam
- Roof insulation and damp-proofing are essential for habitable use
Do You Need Planning Permission?
Most integral garage conversions fall under Permitted Development, provided the external appearance doesn't change significantly. Detached garages or those in conservation areas may need planning permission.
Building Regulations approval is always required, and you'll need structural engineering drawings for the new wall, any beam over the former door opening, and any floor alterations.
