That's a great film and as I live in Kelham Island especially fascinating. About the building on the corner of Green Lane and Dunfields... the original plan was to restore it but the developers decided it was in too poor condition. However, they've since taken it down and rebuilt it entirely and if you see it now it looks almost exactly as it did before. Behind the old bricks it's a concrete structure but you wouldn't know. They've done a great job.
