Portcullis House

Portcullis House is an office building in Westminster, London, UK, that was commissioned in 1992 and opened in 2001 to provide offices for 213 members of parliament and their staff. Part of the Parliamentary Estate, the building augments limited space in the Palace of Westminster and surroundings.
The architects, Michael Hopkins and Partners, published their design in 1993 and the existing buildings on the site were demolished in 1994. At the same time, London Underground was building the Jubilee Line Extension, including a new interchange station at Westminster tube station which occupies the same area; the two were thus designed and built as a single unit. Construction began with works to the existing District line station at sub-basement level. The track had to be lowered slightly and underpinned to allow the extensive excavation to the Jubilee line many feet below. The building above ground began to rise in 1998 and opened in 2001. It is located at the corner of Bridge Street and Victoria Embankment – overlooking the River Thames – and adjacent to the Norman Shaw South Building, which also overlooks the river.
