This temporary pavilion stood in front of the Serpentine Gallery in Kensington Gardens， London for three months during the summer. Therequirement was to provide an area of 300m2 for use as a cafe and for events. Rather than depending on a structural grid system， ourprime objective with this project was to create a structure without internal columns.
The structure is a lattice system made from steel flat bars. Flat bar beams with a depth of 550mm and whose thickness varies accordingto the structural stresses were welded in a factory， panelized in a transportable size， and eventually bolted together on site. Although the structure may at first glance seem random， it is defined by an algorithm of an expanding and rotating square. Each component functionsas an oscillation absorber as well as a structural beam. With each element having an complex interdependence on adjacent elements，overall equilibrium is maintained.
The surface is tiled either with aluminum panels or glass according to the checkered pattern. Without being reduced to architecturalelements such as windows or walls， it appears simple as a decorative pattern.
To cover the space where people gather is a basic task of architecture. It was achieved by utilizing this cubic white box with its infinitelyextending abstract image and intricate but extremely pure system.
