The glazed pavilion, which stands on Peter's Hill Walkway on the north bank of the Thames, has just won planning permission. It will house a vast sculpture by Kapoor: a twin-headed trumpet fabricated in Corten steel. It will also serve as the entrance to the new £5m Salvation Army visitor centre and will act as a contemplative space in its own right.
The visitor centre will occupy the subterranean Bramwell Booth Memorial Hall, site of the Christian organisation's former headquarters. The project also opens up a new "pocket park" in the City of London, and provides a platform from which to view the surviving tower of Christopher Wren's lost church, St Mary Somerset.
Arup is multidisciplinary engineer, Atelier One is engineer to Anish Kapoor, Davis Langdon & Everest is quantity surveyor and Ralph Appelbaum Associates is exhibition designer.
