The Built Green certification program was developed to establish environmental standards for construction materials, energy efficiency, water use and indoor air quality. The voluntary program requires builders to follow a specific set of criteria to attain a Built Green rating ranging from 3-Star, 4-Star, 5-Star or Emerald Star.


We are the only residential developer in Washington state that exclusively builds 5-Star Built Green homes and are leading the charge for green building certification in the region with the completion of the first spec Emerald Star certified home in Seattle, our 100th Built Green certified home.
