Venice, especially with the architecture biennale, is always good early autumn fun. This year promises much, given the gang of nine architects selected by Peter Cook to produce designs for the British Pavilion. The British Council is once again holding an 'international debate', in conjunction with the Architecture Foundation, on the subject of 'How do you boost a city?' - a highly topical theme given the competition now under way for the 2012 Olympic Games, and the plethora of Expos and other promotional events taking place around the globe. The man who has theorised this, of course, is Rem Koolhaas, and he is down to speak at the debate. Book now to avoid disappointment.
