Designed by renowned architect Renzo Piano, the mixed-use scheme will provide 375,000 sq ft of office space as well as 56 private apartments, 53 affordable homes and retail units at ground level. 

Bovis Lend Lease is the main contractor, Stanhope the development manager and Bovis the construction manager. Fletcher Priest is executive architect.

The scheme, which sits on a 0.7ha island site between Oxford Street and Covent Garden and is developed by Legal & General and Mitsubishi Estate Company will also see the redevelopment of a 1960's office block previously occupied by the Ministry of Defence.

It is thought work will complete by the end of 2009.
