Bauhaus brought about the idea of modern architecture to celebrate industrial mass production that considerably reduced construction cost, and to advocate a non-hierarchical formal and spatial structure that was to serve a better purpose in human dwelling in both physical and metaphysical sense. Now in the contemporary era, however, when the Revolution fostered such idea no longer exists, and when accumulation of wealth enabled consumption of diversified architectural expressions, the modern aesthetics, when carried out with expensiveness, has recessed to a mere style. The Bauhaus emphasis on “scientific thinking”, rationality of structure and economical use of materials in architecture, however, has never lost legitimacy over the century. The design of Tian Yun affordable Office was inspired by Ludwig Hilberseimer’s idea, and sought to practise the original meaning of “modern architecture” in a contemporary Chinese urban context. Tian Yun development provides private small and mid-sized research and technological enterprises with office spaces at the fringe of big cities. Although non main economic actors, these private firms are playing an essential role helping to build a solid economy, as Chinese society came to realize after 30 years of a real estate backed economy. Module concept was applied to minimize structure and facade construction cost in order to gain green planted balconies. Rounded corners with the same radian emphasize fluidity. Alteration of two curve boundaries lets more sunlight into interior. The architecture has an overall austere appearance while providing lyrical spatial experiences for individuals at work breaks.
