Hard on the heels of his book The Illegal Architect, Jonathan Hill has edited a collection of essays on users' experience of architecture - Occupying Architecture (Routledge, £17.99). In the introduction he explains that it derives from his teaching activities at the Bartlett, but what, I wonder, do they comprise? Singled out for special mention is student Carolyn Butterworth 'for her decision to lick the Barcelona pavilion'. It was, says Hill, 'one of those special moments when a student extended a project to the limits of its logic, confirming the highest hopes of her tutors'. I wonder what Mies would have thought.
