Founded in 1944 and headquartered in the South Lake Union neighborhood of Seattle, Sellen builds iconic projects for the region’s tech, science, arts, healthcare and hospitality leaders. They believe in building community by creating unique spaces where significant things happen, and in giving back to non-profit organizations that make their community a great place in which to live and work. Sellen operates primarily in the Pacific Northwest and offers a wide range of services from preconstruction support, cost estimating and constructability services, to Virtual Design and Construction (VDC), integrated project delivery and sustainability services. Sellen has a Special Projects group that regularly performs renovations and tenant improvements in existing buildings for a variety of office and health care clients.
