NorthEdge is a four-story, 210,000-square-foot, high-tech office space encompassing an entire block across the street from Gas Works Park. Its rustic yet modern design was inspired by the park and the area’s industrial past.

The building is organized around a 38-foot-wide central outdoor court with a series of small roof terraces and walkways stepping down toward Lake Union. The building’s design strategically stacks all four floors on a 60-foot grade to take advantage of the lake view and Seattle skyline. The multi-story lobby is transparent to frame views for pedestrians — who also have access to a public roof terrace.

This project was built during high volumes of rain and windstorms. Since there was no exterior gypsum sheathing, storms kept coming into the building through the framing and window openings. It made the project challenging for performing interior layout, material handling and staying on schedule.

Lease Crutcher Lewis continuously pushed off water and built temporary dams around the work areas so construction could continue.

With low tolerances for the metal panels, the exterior framing had to be done perfectly. Anning-Johnson used BIM modeling for the exterior framing to minimize mistakes when panelizing on-site.

Judge’s comment: “Modern materials combined with weathered steel panels complement the industrial architecture in nearby Gas Works Park.”
