The residential element of the project has been taken on by City Loft, which will build 160 apartments for developer Landmark.
But the 200-bedroom hotel, in the original plans, has been scrapped.
The mixed-use development consists of a 30-storey tower, which is linked to a separate nine storey building by an atrium. The top 20 floors will be residential, and the rest offices.
The project is due to start on site in July, and should be completed in summer 2005.
