Several UK practices have been selected to design the master plan for a 6ha site within the Nine Elms area surrounding the new US Embassy in London, UK.
The practices, including Farrells, Feilden Clegg Bradley Studios, Allford Hall Monaghan Morris and Flacq, will design the site owned by developer Ballymore.
Farrells is expected to submit a master plan application for the site, along with a detailed design for the first phase by June.
The first phase of the project will include three blocks, ranging from six to 11 storeys, featuring 800 units, retail spaces and a health club.
The second phase of the project involves building 1,000 homes, office space and a large entrance square to the new embassy.
US practice Kieran Timberlake won the competition to design the new £1bn US Embassy building.
Farrells partner John Letherland said collaboration with Kieran Timberlake would now be vital for the project to get the master plan right.
Two other British firms, Arup and cost consultant Davis Langdon have begun work on the 12-storey embassy.
