Psycho Buildings: Artists Take On Architecture" will mark the 40th anniversary of The Hayward - one of the world's most architecturally unique exhibition venues. It brings together the work of artists - including Atelier Bow-Wow, Michael Beutler, Los Carpinteros, Gelitin, Mike Nelson, Ernesto Neto, Tobias Putrih, Tomas Saraceno, Do-Ho Suh and Rachel Whiteread - who create habitat-like structures and architectural environments that are mental and perceptual spaces as much as physical ones.
