Joint owners Deutsche Finance and Yoo Capital aim to create a new cultural hub, complete with restaurants, offices, hotels, an auditorium and open plan spaces.
Plans drawn up by world-renowned design studio Heatherwick Studio and SPPARC architects will see the iconic 130-year-old listed arched glazed exhibition centre refurbished and modernised.
There will also be 600,000 sq ft of new creative offices and studios as well as new restaurants, two hotels and cinemas joining the site.
As a London landmark, there will be increased green spaces throughout the 14-acre site.
After public consultation a planning application will be submitted in September
Mace is also on board the project team offering pre-planning construction advice.
The major build project will be phased and is expected to take around four or five years to complete.
