Ham Green was a recuperation hospital for a long time.
I remember mum being in those blocks!
Don't think the blocks were of architectural importance?! Being WW2 vintage?
So I don't suppose any photos survived 
Yes , my mum was kept in after an op . there in the early 70s and in the days when you were only let out when fit , well and could cope either with or without support , and ' target driven ' was unheard of .
Two grandfathers that died there were both taken post major strokes and one by passing the General and BRI.....mum seems to believe that of the day it was more a mainline local hospital .
Thanks again
