Mace has been selected by developer Stanhope as preferred construction manager for the redevelopment of BBC Television Centre in west London.
Work on the listed building will see the site open to the public for the first time, with new retail, leisure and entertainment space.
The project will include office space, aimed at occupiers in the creative sector and a media business hub, as well as around 950 new homes.
There will also be a cinema, gym, restaurants and cafes.
The BBC will remain at Television Centre operating studios 1-3 through its commercial subsidiary BBC Studios and Post Production, while BBC Worldwide will consolidate its new home at Television Centre, following refurbishment of the Stage 6 building.
Stanhope chief executive David Camp said the team would now progress with enabling works of the first phase of Television Centre for occupation in 2017.
The construction value for the project is believed to around £400m.
Mace chief executive Mark Reynolds said: “Continuing our long-established relationship with Stanhope and Mitsui Fudosan is tremendous and we are looking forward to working with AIMCo, helping everyone transform the iconic Television Centre into a vibrant new community in west London.”
