F5 Tower

A 660-foot Tall Skyscraper in Downtown Seattle

This 44-story high-rise, with its graceful and elegant exterior design, its complementary mix of uses, and its ideal location, will reset the standard for excellence in Seattle. The office space features full-height windows providing spectacular water and mountain views. This unique feature allows for more natural light, resulting in a better working environment for employees. Each floor has been designed with no columns or obstructive bracing, allowing for open, creative plans or heavy build-outs.

F5 Tower is designed to achieve LEED-Gold certification with sustainable features that include rooftop photovoltaic panels and a full-block rainwater reclamation system.

At ground level, a travertine wall creates a podium of natural beauty, a sculpture sits for the public to enjoy, and an extensive living wall for Columbia Street pedestrians to experience.

The space connecting F5 Tower to the Sanctuary features travertine vertical stone quarried from Tivoli, Italy, and bronze paneling. The lobby and connector structural curtain-wall glass is supported by one-inch thick laminated glass fins.

The F5 Tower project also features a 175,000 square-foot, 184 room, contemporary hotel featuring a full luxury spa, 15,000 square feet of meeting space, a 5,000 square-foot ballroom, a sky lounge on the fifth floor, and two upscale restaurants.

After deconstruction of the tower crane running through the interior of the building, smaller cranes, each one smaller than the one before, but having the capacity to remove the preceding unit, were constructed on top of the 600′ structure.

This distinctive zig-zagging “mega-brace” was engineered to support the tower while also offering unobstructed panoramic views of the city; its blue-tinted curtain walls stretch from floor to ceiling with 9.5 foot-high windows.
