Holaday-Parks provided design-build, full mechanical services for this eight-story, historic building located in downtown Seattle, WA. The project included an addition of two full levels and an additional half level (55,000 square feet) of office space; and a 22,000 square foot conversion to retail and restaurant space on the ground level. We designed our mechanical systems to fit around much of the original wooden structure to preserve the historical aspects of the building. This project received the ENR Northwest 2018 Renovation/Restoration Award of Merit, and is LEED® Gold certified.
