The mixed-use scheme was passed over to the London Borough of Sutton by the practice in early November.
The project comprises two residential buildings either side of an existing 17-storey tower office block - known as 'South Point'. An entrance will lead onto a new plaza adjacent to Sutton Court Road, close to the suburb's main railway station.
There will be retail uses on the ground floor of the west, 13-storey tower, facing onto a new public piazza. This will potentially form a new transport precinct linking a proposed future tram/bus station with the railway station behind.
According to the architect, the proposal is intended to facilitate the creation of a new tram link to Sutton, but also 'provide a viable development without such a link'.
If planning is secured, it is hoped that the scheme will start on site in autumn 2006.
