To the coolly beating heart of Swiss Minimalism, Basel, for the opening of an exhibition by what you might have thought of as the most unlikely of practices: Birds Portchmouth Russum. In a cheeky riposte to the international dominance of Swiss functionalism, BPR has injected a generous daub of colour and humour into Basel's sleek architecture museum. And the Swiss, it seems, love it. A buzzing opening reception saw guests tucking into cucumber sandwiches, pale ale and AfterEights while wandering around looking at buildings shaped like prawns, funked-up buses and trams and flyovers suspended on Oldenburgian, elephantine sparkplugs. The practice's Dormasponsored door handles proved a great hit with guests wandering in and out of red-lined booths and ogling the byzantine forms of BPR's weird ironmongery. Looking around the walls at the quirky yet consistently thoughtful designs leaves you wondering why it was left to the Swiss to pick up on BPR's work.
