Cannon Place provides premium office space over Cannon Street Station. The project’s design was inspired by the challenging range of site constraints. The existing station comprises a complex mixture of 1860s brick-vaulted structure and a 1960s concrete-framed redevelopment. Designed by Foggo Associates, the project involved construction of a trussed external frame supporting 21m cantilevers on the northern and southern elevations. The cantilevers and long-span façade truss underwent considerable deflections during construction, and will continue to do so while the building is in service. Displacements were monitored during construction to ensure measurements were in accordance with predictions, and therefore within steelwork installation tolerances.
