China-based firm EID Architecture has been selected as the winner of a design competition for a mixed-use development, entitled Longfor Phase IV, in Chongqing, China. Designed as an exploration of vertical urbanism on a high-density scope, the project is composed of a single tower and associated podium integrated as an assembled massing of stacked box-like volumes. At 150 meters tall, the building will offer office space in its upper levels, and retail on its lower levels.
