Alexandra Pavilion, Alexandra Park, Haringey, London (1980-1981). This project formed the basis for a temporary replacement for Alexandra Palace following a fire in 1980 which destroyed much of the Palace.

Construction was based on the Shelterspan system which was radically adapted. PVC-coated terylene panels are supported on a rigid structure of steel portal frames. The structure was designed to be demountable. Their stable double-curved form prevented wear and tear caused by flapping in the wind. The span of the structure was 118 feet, with external purlins and diagonal rod bracing to provide longitudinal stability. The cascading appearance of the building was derived from the internal organisation, consisting of a large clear-spanned hall and side aisles containing ancillary spaces. Internal climatic conditions are regulated by thermal insulation of the double fabric skin, fan assisted natural ventilation, and gas-powered heating ducted into the space through a functional 'cornice' around the perimeter of the enclosure.
