Hudson Pacific Properties, Inc. Seattle

450 Alaskan

Located in historic Pioneer Square, 450 Alaskan has a front row seat to the multi-year program to re-build Seattle’s waterfront.

The eight-story building marries modern Class A office space with the eclectic charm of the city’s oldest neighborhood. A rooftop deck with conference center and amenity space enhances the workplace experience. The jewel in this crown? Unbeatable Sound and mountain views, of course.

In addition to ground level retail and two levels of below-grade parking, the brick-clad building is home to Pacific Northwest based Saltchuck. The tenant improvement for their headquarters took place in conjunction with the shell + core and features open offices with ample natural daylight, large relites and door openings, and a feature staircase that surrounds a 30-foot totem pole crafted by a Bainbridge based master woodcraftsman.

Approach Spotlight

Ensuring the character and historic principles of neighborhood remained intact

Preserving Character

Critical to this project’s success? Preserving the character of the neighborhood. Before a shovel hit the ground, stakeholders went before the Pioneer Square Preservation Board seeking approval to build. An arduous review process and community stakeholder input helped to ensure character and historic principles of neighborhood remained intact.

Working Within Close Quarters

450 Alaskan was one of the first new development projects on Alaskan Way prior to the infamous viaduct demolition. Building four feet away from the viaduct—and drilling within a foot of its foundations—presented its own set of challenges. The team partnered with Seattle Tunnel Partners and WSDOT to develop safe and effective solutions regarding shoring, dewatering, vibration control, and traffic safety during construction.
