Rossendale has conservation areas including Rawtenstall, Bacup, Whitworth, and Haslingden. Listed buildings cluster around former mill sites and parish churches. The South Pennines cover most of the borough, with extensive moorland constraints on elevated land. Flood zones apply along the Irwell and its tributaries. The borough is overwhelmingly Victorian stone-built terraces in narrow valley settlements with moorland above. Materials and detailing are closely scrutinised in conservation areas.

Get personalised guidanceConservation Areas & Listed Buildings
In conservation areas, the side element of a wraparound extension is not permitted development. The rear element is limited to 3 metres depth.
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.
Check if your property is in a conservation area or has other planning constraints.
