Good example David.
Another element of the builds in the town is the fabric of the buildings and mills. Vast majority pre WW1 are Tubber hill stone. The only major departure is the retaining wall of the old railway yard, now the Pioneer car park, which is Rainhall Rock limestone. In the late 19th century and early 20th there was a brickworks at Park Close quarry on Salterforth Lane but according to Harold Duxbury, very bad brick suitable only for interior lining of stone built houses. The only surviving buildings that I can think of in this brick is the range of buildings on Commercial Street including the old Shambles. The stables below were built of the same brick.
There was a brief affair with Accrington brick, the Co-op buildings in West Close Road, bungalows on Greenberfield Lane, the Model Lodging House in Butts and fire station, in the 1920s and 30s and since then planning has forced the use of reconstituted stone facings with the ubiquitous breeze block linings. The most peculiar aberrations in the district I can think of are the pantile roof on an outbarn close to Broughton roundabout and of course the crazy thatched roof of the new pub next to Nelson and Cole College! Thankfully nothing like that in Barlick. Perhaps the worst eyesores in the town are the two banks and what used to be the Labour Exchange on Church Street and the Post Office Corner buildings. I'd support any move to demolish any of them. 1950s of course.
The point is of course that if you know about the materials you can make a good stab at a building date, especially of you make distinctions between rubble and dressed stone. Mat Hartley liked his ashlar around 1900.....
