Housebuilder Berkeley Homes and Southwark London Borough Council have chosen Squire & Partners to draw up new plans for the Potters Field site, on the south bank of the Thames in central London.
The previous scheme on the site, designed by Ian Ritchie Architects, featured eight 18 storey towers on the site.
But it fell foul of planners at Southwark Council who refused to give the complete scheme their backing.
In March, Berkeley agreed to go back to the drawing board, picking three firms to work up early proposals for the site, a process that has resulted in Squire & Partners appointment.
The firm will now come up with initial designs by the summer which will then go out for public consultation.
