Arup, a global design and consulting firm, plans to relocate its Seattle offices to 25K SF in the Second & Seneca building at 1191 Second Ave. Arup will occupy the entire fourth floor. The company currently occupies 8,500 SF in the Millennium Tower at 719 Second Ave. It plans to move by the end of this year.

Arup chose the Second & Seneca building due its downtown location and proximity to mass transit and the ferry terminal. The building allows for an open-concept office space and collaborative environment with a trendy industrial vibe.

“Our office has doubled in size in the last three years and we look forward to continued growth,” said Joshua Yacknowitz, principal and Seattle office leader at Arup. “We are committed to our local community, building upon our recent rewarding projects with the Pike Place MarketFront, the University West Campus Utility Plant, the current Washington State Convention Center addition and the Space Needle restoration.”

Colliers International’s Tony Ford acted as supervisor to Arup in the lease process and negotiations.
