During the fifties, precast reinforced concrete houses were built to alleviate the nationwide housing shortage. This particular type is easily identified by the enveloping roof, and was known as the Cornish style. 
The roof makes this a slightly challenging kit to construct but it is sold in packs of two (ie. 4 houses) . so you have a spare to practice with! The houses are complete models, not half relief.
Spare doors in different colours are supplied so you can easily build a whole estate. Each pair of houses has a 'footprint' approximately 5.7" x 2.7".
