I was living in a 2 up-2 down terraced house in Cheetham hill around the time that these prefabs were being built. The estate was quickly built in the main, by men of different nationalities from the nearby 'Prisoners of War' camp. The prisoners could be identified by the large yellow square worn on the back of their jackets!
Many of the prefabs were allocated to families who had been made homeless by the bombs which fell on Manchester and in the area of Salford Docks.
I remember walking around the estate with my mother and seeing the wishful look on her face. The prefabs had gardens, hot water systems, bathrooms and inside toilets. This was a far cry from the slum properties so many families, like mine were living in during the 1930s/40s/50s/60s.
