During the station's redevelopment, a vast 39 m (127 ft) deep void was excavated underneath the old station to house the escalators, lifts and stairs to the deep-level Jubilee Line platforms. This made it the deepest ever excavation in central London. One of the most difficult problems the engineers faced was to construct the station around the Circle and District line tracks, which continued in service throughout its construction. The tracks had to be lowered by 300 mm (1 foot), an operation achieved a few millimetres at a time during the few hours each night that the system was closed. The station was by far the most complex in terms of engineering of any of those on the Jubilee line and it was the last to open, just before Christmas 1999. Nothing of the old station remains.
The station's cavernous design, by Michael Hopkins & Partners, won it a 2001 Royal Institute of British Architects Award and earned it a place on the shortlist for the RIBA's prestigious Stirling Prize. The station has an extremely austere interior, comprising gigantic concrete beams and columns criss-crossed by stainless steel escalators and floors, giving it a distinct "space-age" look. The reason for the presence of so many structural supports is because Portcullis House, home to the offices of many MPs, is located immediately above the station, so it bears a significant weight.
As with other stations on the Jubilee Line Extension, the Jubilee Line platforms at Westminster have a glass barrier, with its own set of sliding doors, between the platform and the tracks to assist in controlling air circulation (and presumably, extra safety). The platforms are some 32 m (104 feet) below ground level, making them among the deepest on the Underground network. Because of the limited amount of space on the site, the two tunnels are "stacked" on top of each other rather than the normal side-by-side arrangement.
