FAQs
Garden Rooms & Offices in Lewes: FAQs
Do you provide garden rooms & offices 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 for a garden room?
Most garden rooms fall under permitted development provided they are single-storey, set back from the boundary where required, and stay within height and garden-coverage limits. Larger structures, those closer to a boundary, or on designated land may need a full application, which we check for your specific garden.
Can a garden room be used all year round?
Yes, provided it is properly insulated in the walls, roof and floor and fitted with heating — this is what distinguishes a garden room from a summerhouse or garden shed, which are not designed for year-round comfort.
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.
