Seattle
In 1988 we opened our Seattle office. Home to global giants such as Starbucks, Microsoft, Amazon, and Boeing, the region also has a large architectural community that shares our eco-sensitive, cost-efficient design philosophy. Seattle has several active technical societies of which we’re members including ASHRAE Puget Sound, Cascadia USGBC, and the Seattle 2030 District group – one of the nation’s first high-performance building districts focused on meeting Architecture 2030 targets.
