This is Dutch architect Maxwan's vision for motorwayside housing in the year 2030. The practice submitted the design to an ideas competition held by the Netherland's Ministry of Transport, which is looking for ways to develop land along the country's major transport routes. The design is just one of the projects on show at the first International Architecture Biennale in Rotterdam. The biennale, which opened this week and runs until 7 July, is entitled "Mobility: A Room with a View" and presents transport routes as the new frontier of architectural design. Among the exhibitions are studies of transport routes in 10 of the world's major cities. Architects speaking include Zaha Hadid, Dominique Perrault and Greg Lynn.
