Mansell has won a £5.7 million contract for the design and construction of 36 new homes at Lyme Grove in Hackney, London.
The contract has been awarded under the North River Alliance framework and will involve the demolition of an existing building and the construction of an eight-storey tower.
It will house 27 one, two and three-bed flats and a row of nine townhouses, comprising three and four-bedroom homes.
Demolition will start on site this month with construction scheduled to begin in mid-July. The project is due to be completed in October 2010.
The scheme has been designed to achieve Level 3 of the Code for Sustainable Homes.
