Reflecting the urgency of the problem, housing was initially prefabricated. Construction of 7,631 permanent homes, housing 25,000 people, began in 1948 and was complete by 1958. The development is fairly low density with large sections of parkland retained in the centre and edges of the estate. The estate was constructed primarily in brick, with mostly terraces of houses and some flats. Provision was made for community facilities and three shopping areas were planned to break up the size of the development. Some industrial development already existed to the south and adjacent to the A12 road and this was retained.[citation needed]
