Architecture on and around water is the subject of this RIBA talk, which looks at the ways in which living on water has long exercised designers' imaginations – from Buckminster Fuller's Triton City to Kiyonori Kikutake's Marine City. Speakers including architect Alex de Rijke and Mike Luddy from the Royal Docks Management Authority talk about whether water-based communities are becoming a realistic proposition rather than just a utopian dream and if one day we'll see the likes of London's Royal Victoria Docks developed as viable floating communities complete with businesses, homes and services.
