Windows and doors fitted across Darwen

Darwen sits above Blackburn and the housing changes with the height. Where Blackburn is brick, Darwen has far more stone: mill owners' houses at the top end and modest stone workers' terraces below, mostly Victorian, with a large layer of post-war housing behind it. The town centre conservation area, designated in 1995, looks closely at fenestration and roof form, so replacement there is a specification question rather than a straight swap. Darwen also still has a working terracotta industry, which tells you something about the detailing you find on the better frontages.
