Sellen Construction

Since our founding in Seattle's South Lake Union neighborhood in 1944, we have played a role in the phenomenal growth of this region. Today, we are one of the area's most successful builders and have the good fortune to work with some of the most significant organizations in the Pacific Northwest.

While Sellen is often recognized for our work on larger projects, we actually complete more tenant improvement projects year in and year out than any other type of work. We have a team of tenant improvement experts who have dedicated their careers to this work and possess the creative problem-solving skills necessary to deliver projects with maximum efficiency. Sellen Special Projects combines the agility and responsiveness of a small firm with the full resources of a leading local builder. Our philosophy is simple: there's no project too small for the right client.

Sellen has spent the past 75 years building a culture based on partnerships, community and always acting in the best interests of our clients and projects. Our purpose is to improve the lives of those around us - as builders, partners and neighbors. We are guided by our core values of safety, people, craftsmanship, performance and community.

Sellen's purpose is to improve the lives of those around us - as builders, partners and neighbors.
