F5 Tower
660-foot-tall skyscraper in Downtown Seattle, Washington
About
F5 Tower (previously The Mark and Fifth and Columbia Tower) is a 660-foot-tall (200 m) skyscraper in Downtown Seattle, Washington. It consists of 44 floors and is the sixth-tallest building in Seattle.
The tower consists of 516,000 square feet (47,900 m2) of office space leased entirely by F5 and a 189-room luxury hotel operated by Lotte Hotels & Resorts. The hotel, initially planned to open in 2017 under another operator, was officially opened in September 2020. It was designed by Zimmer Gunsul Frasca and was being developed by Daniels Real Estate. While it was being built during Seattle's historic building boom, the F5 Tower was the most expensive building under construction.
