Cheshire West and Chester includes the historic city of Chester, where extensive conservation area coverage, Roman and medieval listed building density, and the Grade I listed city walls make planning exceptionally tight.

Green Belt covers substantial rural areas. Professional planning advice is strongly recommended for any alteration in Chester's historic core.

Conservation Areas & Listed Buildings

In conservation areas, roof alterations that change the appearance of the roof may be more tightly controlled. Materials should match the existing roof.

Conservation areas

Properties in conservation areas often have reduced permitted development rights. Some project types (like side extensions) lose PD rights entirely. An Article 4 Direction can remove additional PD rights.

Listed buildings

Listed buildings (Grade I, II*, or II) have no permitted development rights at all. Any external alteration requires Listed Building Consent in addition to any planning permission. An architect experienced in heritage work is essential.

Check if your property is in a conservation area or has other planning constraints.
