Is the centre of Dorchester a conservation area?

Yes. Dorchester has an extensive conservation area covering the historic town centre. PD rights are reduced for side extensions and cladding changes. Rear extensions usually retain PD rights but should use sympathetic materials. We assess your property against the conservation area boundary.

Are there Roman archaeological concerns in Dorchester?

Dorchester has significant Roman archaeological remains. Ground disturbance (foundations, drainage) in the town centre may trigger an archaeological condition. The council may require a watching brief during excavation. This adds modest cost but rarely prevents an extension.
