Designed not only for the opening of Buckingham Palace to visitors in summer, but for garden parties, exhibitions and other events, the canopies are based on the 3.60 m modular dimension of the palace. The system consists of a steel framed base with a hardwood deck, in the middle of which is a tubular aluminium column supporting the actual canopy. The central column also acts as a drainpipe, conducting rainwater from the white canvas covering into the ground. Slender tie rods at the corners of the umbrella serve to resist wind loads.
