2DEFINE Architecture, with local partner Dalian Urban Planning & Design Institute, recently won an assignment to lead the design of an extraordinary new convention center in Yingkou, China. The project consists of a four-story, 70,000-square-meter (750,000-square-foot) facility in a city of 2.2 million people located in the northwest province of Liaoning on the Bohai Sea. A unique, sea urchin-shaped building created to reflect its natural environment, the facility will be the centerpiece of a new harbor created off of a satellite central business district in the port city. More images and architects’ description after the break.
