Garage Conversions in Crawley
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 Crawley, that covers Ifield, Three Bridges, Southgate, Furnace Green, Broadfield, Pound Hill, Maidenbower, Northgate, West Green, Langley Green, Tilgate, Gossops Green, Bewbush. Crawley combines postwar new-town neighbourhoods with older pockets around Ifield, Three Bridges and Southgate, and sits close to Gatwick Airport with strong transport links into London and along the M23. Housing stock ranges from 1950s–70s estate homes to Victorian terraces and more recent developments, which means project requirements vary considerably from one street to the next.

Property styles in Crawley
Crawley's housing mix includes postwar semis and terraces across the New Town neighbourhoods, Victorian and Edwardian houses around the older Ifield and Southgate areas, and newer estate housing on the town's edges. Many properties are well suited to rear or side-return extensions where garden depth allows, and loft conversions are common in the older stock.
Planning considerations
Crawley Borough Council is the local planning authority. Ifield village and parts of the old town centre fall within conservation areas, which affects permitted development rights and materials on visible elevations. Properties near Gatwick Airport may also be subject to safeguarding or noise-related planning considerations, which we check at feasibility stage.

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 Crawley: FAQs
Do you provide garage conversions across all of Crawley?
Yes, we cover the RH10 and RH11 postcode areas in full, including Ifield, Three Bridges, Southgate, Furnace Green, Broadfield, Pound Hill, Maidenbower, Northgate, West Green, Langley Green, Tilgate, Gossops Green, Bewbush.
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.
Do you cover both RH10 and RH11 in Crawley?
Yes, we work across both postcode areas, including the town centre, Ifield, Three Bridges, Southgate, Furnace Green and the surrounding neighbourhoods.
