City Tower is a 21 storey, RC framed office building which was built in 1960. The design was inspired by the Seagram Building in New York and City Tower is the last surviving of five similar towers on London Wall. The proposal included rebuilding the podium structure, enlarging the reception structure both in width and creating a double-height space and creating several large openings through the tower core structure. A key challenge was the analysis and construction of the two reception stairs. Both were designed to be as elegant and slender as possible while maintaining appropriate serviceability levels. The project reached completion in August 2013.
