Garage Conversions in Sevenoaks
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 Sevenoaks, that covers Riverhead, Dunton Green, Weald, Bat & Ball, Kippington. Sevenoaks is an affluent Kent town close to the Kent Downs National Landscape and extensive Green Belt land, with a historic core, well-established residential streets of substantial detached and semi-detached houses, and strong rail links into London.

Property styles in Sevenoaks
Sevenoaks has a significant stock of larger detached and semi-detached Victorian, Edwardian and interwar houses on generous plots, which frequently suit substantial rear or double-storey extensions and outbuilding conversions.
Planning considerations
Sevenoaks District Council is the local planning authority. A large proportion of the district is designated Green Belt, and parts fall within the Kent Downs National Landscape, both of which place additional constraints on new structures and extensions beyond normal permitted development limits.

FAQs
Garage Conversions in Sevenoaks: FAQs
Do you provide garage conversions across all of Sevenoaks?
Yes, we cover the TN13 postcode area in full, including Riverhead, Dunton Green, Weald, Bat & Ball, Kippington.
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 Green Belt designation affect extending a house in Sevenoaks?
Green Belt policy applies primarily to new buildings and significant additions that would be disproportionate to the original dwelling, rather than ruling out modest extensions. We assess this against your specific property and its planning history.
