This collaboration between artist and architect will provide London with a new Thames-side landmark.
TO BE Set halfway between St Paul's Cathedral and the Tate Modern, on the pedestrian thoroughfare created by the Millennium Bridge, this design collaboration between sculptor Anish Kapoor and architect John McAslan draws on the spirituality of both art and religion. "We thought we could make a spiritual connection between St Paul's and the Tate," says McAslan.

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.
