Form and function converge in inspired ways throughout our Class A, luxury office tower. From light-soaked workspaces with flexible configurations to inviting common areas and elite on-site amenities, we've curated an environment that enhances the professional quality of life as well as productivity. One of the first urban office towers to model high-technology going vertical, the tower is fully leased by F5.

The 48 story high-rise tower is already adding to the Seattle skyline with its sophisticated and stunning architectural design.

On the ground, quality urban design is also underscored. A Travertine wall hand selected by the Daniels team in Italy creates a podium of natural beauty. At the corner of 5th Avenue and Columbia Street, a sculpture commissioned by the internationally renowned and local artist, Julie Speidel sits in the public domain for all to enjoy.  And if you turn the corner to walk down Columbia Street, you will be greeted with an extensive living wall of flora and fauna.

In 2018, The Mark Tower will debut a 189-room luxury hotel and spa fashioned by the world-class designer Phillippe Starck, bringing intelligent sophistication and nightlife to the downtown business district.
