Japanese starchitect Shigeru Ban's Paper Tea House reached £31 700 at a Phillips de Pury and Company auction of contemporary Japanese art. Designed for indoor use and measuring just over 5m, the house contains a table and four stools, and also features a waiting area with a bench, in keeping with tea ceremony practice. Unusual in Ban's paper architecture oeuvre, the house uses an interlocking square structure, rather than the typical tubes.
