Garage Conversions in Lewes
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 Lewes, that covers Cliffe, Southover, Landport, Nevill, Malling, Wallands. Lewes is the historic county town of East Sussex, built on a steep hillside above the River Ouse within the South Downs National Park, with a dense concentration of listed and historic buildings in its centre.

Planning considerations
Lewes District Council is the local planning authority, and the town sits within the South Downs National Park, which has its own planning authority function for certain matters and places significant weight on landscape and heritage impact.

FAQs
Garage Conversions in Lewes: FAQs
Do you provide garage conversions across all of Lewes?
Yes, we cover the BN7 postcode area in full, including Cliffe, Southover, Landport, Nevill, Malling, Wallands.
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.
How does South Downs National Park status affect building work in Lewes?
Development within the National Park is assessed with particular regard to landscape character and setting, alongside normal planning policy. Combined with the town's conservation area and listed building status, this means early advice is particularly valuable in Lewes.
