Garage Conversions in Horley
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 Horley, that covers Massetts, Lonsdale, Smallfield, Horley Row, Westvale Park. Horley sits close to Gatwick Airport, with a historic village core and substantial 20th-century residential development around it, making it a popular area for family homeowners looking to extend rather than move.

FAQs
Garage Conversions in Horley: FAQs
Do you provide garage conversions across all of Horley?
Yes, we cover the RH6 postcode area in full, including Massetts, Lonsdale, Smallfield, Horley Row, Westvale Park.
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.
Does living near Gatwick Airport affect planning permission in Horley?
Some development types near the airport are subject to safeguarding consultation with the airport operator as part of the planning process. This does not apply to all projects, and we advise on the specific position for your address.
