No, these buildings are not happy to see you. MVDRV architects recently won the Gwanggyo City Centre Competition with their design of this incredible new city just south of Seoul, South Korea. The proposed complex is a fully self-sufficient city for up to 77,000 inhabitants. Similar nodes, common in South Korea, concentrate residences, work and play all in one interactive center, reducing dependency on auto or train travel and building a strong sense of community. MVRDV's masterplan provides space for housing, offices, shops, and educational facilities. Designed as a cluster of structures rising up in concentric rings, each floor in the city is lined with lush box hedges that improve ventilation while reducing energy and water usage. An internal irrigation system stores extra water from the buildings and uses it to sustain these green facades. MVRDV states: “This diverse program has different needs for phasing, positioning and size. To facilitate this all elements are designed as rings. By pushing these rings outwards, every part of the program receives a terrace for outdoor life.” The concept is currently being reviewed for development and feasibility at Gyeonggi provincial authority's Urban Innovation Corporation. Development is to be completed in 2011 and construction will start shortly after.
