The project, which has been granted outline planning by Bath and North East Somerset Council, will provide 2,200 homes on one of the country's largest brownfield sites.
Backed by developer Crest Nicholson, FCB's designs for the scheme have caused controversy due to some of the buildings being nine storeys high.
The images reveal the first phase of the development at Victoria Bridge, which has been submitted for detailed planning approval and is out for public consultation.
But the document cannot be given formal backing until the full project is supported by the government. The proposals are a departure from the city's 'local plan' and many of FCB's designs have come under fire from heritage groups and local campaigners.
However, it is unlikely the government will block the development of a brownfield site, following Prime Minister Gordon Brown's push for new affordable housing outlined in a speech last week.
Brown is calling for 80,000 new homes to be built each year, with 3 million built by 2020 to accommodate a 'growing housing need'.
