The sweeping building design contains varied and dynamic roof slope angles necessitating a flexible green roof solution provided by XF301 precultivated vegetation mats and system assemblies custom-tailored by Xero Flor America for the structured complex roof microhabitats. The Multi-Structured Washington State Private Residence was completed in November, 2006.
