Garage Conversions in Guildford
A garage conversion changes an integral or attached garage from vehicle storage into habitable space — such as a playroom, home office or bedroom — by upgrading the floor, insulation, damp-proofing and services, and replacing the garage door with a matching wall.
In Guildford, that covers Onslow Village, Merrow, Burpham, Stoughton, Westborough, Charlotteville, Shalford. Guildford is Surrey's county town, with a historic cobbled High Street, a substantial university population, and residential areas ranging from Victorian terraces near the centre to larger detached houses in the surrounding hills, close to the North Downs and Surrey Hills.

Planning considerations
Guildford Borough Council is the local planning authority. The historic town centre and several residential areas are conservation areas, and parts of the borough fall within the Surrey Hills National Landscape, affecting design and materials for visible extensions.
How it works
Our garage conversions process
- 01
Feasibility survey
Checking the existing floor, walls, roof structure and damp-proof course, and confirming what services need extending.

- 04
Fit-out and completion
Extending electrics and heating, plastering and decoration, finishing with Building Control sign-off.

FAQs
Garage Conversions in Guildford: FAQs
Do you provide garage conversions across all of Guildford?
Yes, we cover the GU1, GU2, GU3 and GU4 postcode areas in full, including Onslow Village, Merrow, Burpham, Stoughton, Westborough, Charlotteville, Shalford.
Do I need planning permission to convert my garage?
In most cases no, provided the external appearance and the building's footprint stay the same — this typically falls under permitted development. If you're altering the external walls, adding windows to a street-facing elevation, or the property has restricted permitted development rights, a planning application may be needed, which we confirm at survey.
Will my garage conversion need Building Regulations approval?
Yes. Bringing a garage into habitable use always requires Building Regulations approval, covering the floor, insulation, damp-proofing, ventilation, electrics and, where relevant, fire safety between the conversion and the rest of the house.
Are there conservation areas across Guildford?
Yes, several, including the historic town centre and parts of some residential neighbourhoods. We check the position for your specific address as part of the feasibility assessment.
