THE SIXTYK Consortium, led by Crest Nicholson and architect Sheppard Robson, unveiled its £60,000 house prototype this week at the Building Centre in London.
The group is one of six to win John Prescott's Design for Manufacture competition, which aims to increase the supply of affordable housing by using modern construction methods.
The house was built using Kingspan's TEK structural insulated panel system.
Project manager Alan Shingler of Sheppard Robson said: 'It took three days to bolt the frame together. After that it was watertight and we could work on the outer shell.'
The consortium has developed 35 styles, including options for three and four bedroom houses.
Mr Shingler said the larger houses would be 'effectively the same cost per metre' to construct. The SixtyK Consortium has been chosen as developer for two of the nine sites in the competition.
