The project involved the restoration of the Ceperley Rounsfell Building of 1921 and the retention of the facade of the Royal Financial Building of 1929. The tower comprises twenty-six storeys of apartments above eight storeys of offices, with shops at street level. In contrast to the smooth facade of the offices, the apartment floors curve outwards in four wide bays, which step vertically to provide shade and mountain views. The plan supports a variety of apartment types, with the living spaces focused on the window bays. All the apartment interiors have been designed by the practice, with variations of Foster kitchen and bathroom fittings. At the top of the tower, duplex penthouses have landscaped terraces.
