Five international architects renowned for their cutting edge thinking, including David Adjaye (UK), Atelier Bow-Wow founders Yoshiharu Tsukamoto and Momoyo Kajima (Japan) and Joe Osae-Addo will join a host of innovative South African architects as speakers at the Architecture ZA 2012 Biennial Festival, to be held at Cape Town City Hall, from Thursday, 13 September to Sunday, 16 September. In partnership with the South African Institute of Architects (SAIA), Cape Town Institute for Architecture and associate sponsors PPC, the Cement and Concrete Institute, Lafarge and Paragon Architects, the festival is a veritable think-tank of international and local speakers, that also includes debates, master classes, exhibitions, a film festival and city tours. Architecture ZA 2012 follows on the success of the 2010 Biennial, which took place in Newtown and attracted more than a thousand delegates.
