Rirkrit Tiravanija has created the second Ng Teng Fong Roof Garden Commission artwork for National Gallery Singapore. Featuring an interlocking bamboo structure with a simple wooden tea house at its centre, this site- specific installation springs from the artist's interest in fostering social engagement and human interaction through art. With homes in Chiang Mai, New York and Berlin, Tiravanija's nomadic life is a constant negotiation of cultures, and a source of inspiration for his practice. This catalogue illuminates this influential artist's fascinating oeuvre through newly commissioned essays and full-colour images of the installation.
