David Greene has been hugely influential for generations of architects, as an educator, architect and founder member of Archigram. Greene, working in collaboration with Samantha Hardingham, who also co-authored the accompanying AA publication L.A.W.U.N Project #19, invited a number of designers to revisit some of his signature projects, reviewing their context in relation to contemporary construction and digital techniques. Both book (designed by Zak Kyes) and exhibition explore Greene's interest in how new technologies inform new architectures by demonstrating his increasing disinterest in form and a wilful drift towards invisibility. AA tutor and artist Shin Egashira looks at Greene's thesis project 'A Mosque for Baghdad' (1958) with a view to designing an appropriate fabrication technique. Theo Spyropoulos, DRL co-director and founder of minimaforms, explores Greene's 'High-Rise Pods' project. Textile sculptor Rowan Mersh designs the very first 'hairy coat' - more communications habitat than garment. This full-scale prototype is a manifestation of Greene's audio-visual piece 'The World's Last Hardware Event' (1967). Finally, filmmaker Nic Clear edits a new version of a short film about the 'Invisible University', with footage collected by Greene, Hardingham and Mike Barnard. Brett Steele mediates an evenings conversation between David Greene and the designers and collaborators of the book and exhibition. NB: Sound and image slip out of sync towards the end.
