Mace has won a £19.3 million deal to design and build student accommodation in east London.
The contractor was appointed by Fieldgate Street Investment for the work at 14 Fieldgate Street.
The development comprises 339 student rooms, nine residential apartments, a reception and ground level retail areas.
Work is due to start on site this summer, with completion scheduled for early 2012.
The accomodation will feature reinforced concrete up to the second floor and a light-weight steel framework on the floors above. Pre-fabricated bathroom pods will be installed to reduce the waste produced on site.
