Garden Rooms in Lewes

Lewes sits inside a national park

Much of Lewes and the villages around it fall within the South Downs National Park, and the town itself has one of the largest conservation areas in Sussex, covering its Georgian and Regency streets. Both can affect what a garden room is allowed to look like, not just whether it needs an application.

We check the National Park and conservation area boundaries against your address at the survey stage, so the design starts from what will actually be acceptable rather than working backwards from a refused application.

Chalk downland ground

Gardens on the downland edge of Lewes typically sit on chalk, which drains fast and can be shallow over bedrock on higher ground. We test bearing and drainage before finalising the base, so the room does not move or pond after a wet winter.

• Foundation design checked against chalk depth and bearing on site
• Materials and finishes chosen with National Park guidance in mind
• Cladding and colours that sit comfortably against traditional Lewes streetscapes

Planning permission around Lewes

Permitted development still applies to most single-storey garden rooms within the National Park, but the South Downs National Park Authority has its own design guidance, and Article 4 directions apply in parts of the district. We establish which rules apply to your specific address before quoting, not after.
