Xuhui Waterfront CBD is a 500,000 square-meter mixed-use project in Shanghai. I was the project architect from 2014-15. The development consists of four office towers and a large retail podium. The entire project is modeled in REVIT, a parametric BIM tool, and design studies are conducted in Rhino, a freehand-style, flexible design software. While the towers are mainly rational square-ish floor plates optimized for efficiency, the retail podiums take advantage of a "courtyard" concept, with retails cubes balancing open green space in an yin and yang fashion. The curtain walls of the towers transitioned into horizontal "drapes" to cover the courtyards and provide protection of the weather, and to create semi-outdoor experience.
