Get personalised guidanceConservation Areas & Listed Buildings
In conservation areas, changing window materials (e.g. timber to UPVC) or styles may need planning permission. Listed buildings always need Listed Building Consent for any window or door changes.
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 (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.
