A relative of my father Ted Francis, lived in 413 Wake Green Road Moseley. I visited him into the 1980s. His prefab was renovated and I understand a lady lived there subsequently. It is an unusual design with many original features. These prefabs are grade two listed (not that this will protect them) They were open to the public on heritage days in 2016. Are any of them lived in now? I was last there a couple of years ago, but the condition of unoccupied buildings change rapidly.

The Prefab museum is on-line, but a fund of information.
You can go inside a prefab at Avoncroft Museum of Buildings near Bromsgrove.
I hope some at least in Wake Green can be saved. Ted's had a fitted kitchen and was all electric. He lived there for many years with his cat.
I see from the Feb Mail article that some are still lived in.
