Broadgate Exchange House is a mixed-use building in London, designed by Skidmore, Owings and Merrill (SOM) it was completed in 1990.
The steel and glass structure references modernist-style. The building integrates a 78-metre long rail yard, becoming a hybrid bridge-building with the arching steel structure.
The building is situated on top of Liverpool Street Station in London, the arching design allowing the function of the trains beneath a 10-storey office building.
The skeleton of the structure is formed by four parallel archways which enables a column-free interior. These parabolic arches sit against a grid of glass, creating two fundamental geometric elements to the architecture - the grid and and the arc.
The Broadgate Exchange House is one building within a larger Broadgate Development which had master-planning also by SOM.
The building was the recipient of the 2015 American Institute of Architects - Twenty-five year Award.
