The pavilion was originally designed by Kengo Kuma in 2005 in honour of Furuta Oribe, the famous Japanese master of tea ceremonies. Constructed entirely in polycarbonate, the tea house measured roughly 6 ? 3.4 m. The original structure, consisting of 92 polycarbonate hollow cellular ribs 5 mm thick and set at 5.5 cm centres, formed an organically shaped translucent enclosure that allowed light to penetrate to the space within.
