I bumped into my old friend Tim Pyne, design guru for the best bits of the Dome, in the Fulham riverside Sainsbury's, and quizzed him about his current activities. He has been working on prototypes for pod housing in a creative dialogue with his architect. 'He seems to think it's his project, ' groans Pyne, an architect himself who should be used to this sort of thing. Still, he is an exemplar of someone who believes in prefabricated, minimal-space residential property. He arrived at Sainsbury's by houseboat!
