The height of the scheme has been reduced following a public exhibition, despite Wilkinson Eyre winning planning permission for a 40-storey skyscraper adjacent to the site.
The tallest of the towers on the site, which stood at 32 storeys, has now been reduced to three buildings of nine, 14 and 17 storeys.
A 26-storey tower has been replaced with four pavilion-style buildings each of 10 storeys, and a further 15-storey structure has been reduced by six storeys to sit beneath the cliff height.
The £300 million scheme will deliver more than 1,300 homes, 40 per cent of which will be affordable housing.
A spokesman for the delivery group, Brighton Marina Regeneration Project, said: 'We have been listening to residents right throughout the process.
'We had a particularly unusual start to the scheme, as we held a public exhibition without any designs, just to get a feel for what people were looking for from the project.
'This really is a regeneration project. We had 1,300 people come to our various public displays, who were talking to the design team, and this is the latest response from the designers.'
The regeneration team will submit the designs for planning by mid-December, with hopes of construction starting on site by next spring.
