Recovering some old photos the other day, I found this one taken at Welshpool back in 2010.
Home to the Powysland Museum, the building is a genuine canal warehouse on the Montgomery Canal. The building was extensively restored in the 1980s, the work being very sensitively done as this photo from the Victorian Powys website shows.
Apart from that, I'm struggling to find much about the history of the building itself. At least this is a genuine warehouse, and a railway one at that.
Loads of modelling potential - nice square building with stone-topped windows and no fancy brickwork.
