I recently happened across this rather candid audio clip in which Mr Ray Newman remembers his childhood in a post-war prefab and later in a council house in Somerset. Pros and cons, with some colourful language!
Personally I do remember condensation and frost on the windows, but I suppose our prefabs in Pilgrims Way must have been better equipped than Ray’s. Cooking and water-heating were electric. There was even a fridge in the kitchen. A sold fuel (coke) boiler in the living room kept us reasonably cozy in winter. Ray’s memories of fresh air and the countryside do chime though.

..ah..’memoirs’ I will read all..
OK! If you want to write about your prefab experiences, I’ll certainly consider publication here if you like.
