Greater London Council. Department of Architecture & Civic Design
NOTES: Constructed on a roundabout on the south side of Westminster Bridge, this concrete and glass hexagonal structure was an annexe of County Hall, headquarters of the Greater London Council (GLC). It was connected to the main building on the south bank of the River Thames by an enclosed elevated walkway and pedestrian subways under the busy traffic gyratory system. With the abolition of the GLC in 1986, it became disused and was demolished in 2006 to make way for a hotel.
