In 2011 RaT were commissioned to redesign a two bedroom apartment in the Manhattan Lofts Bankside development for a private client. The design features a cantilevered glass box which projects out above the living and dining areas below. The glazed upper level of the duplex apartment houses the master bedroom and boasts 180 degree views out across the skyline of London's square mile. The cantilevered portion of the toughened glass floor is supported by new structural steel beams which are tied back to the original concrete frame of the building.

In addition to the complex structural alterations, RaT also redesigned the apartment's bathrooms, kitchen, and living area.
