The tower consists of 516,000 square feet (47,900 m2) of office space leased entirely by F5 Networks 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.
The tower was built next to the former First Methodist Episcopal Church. Although the education wing was demolished to make room for the tower, the remainder of the former church building has been preserved and has since been re-purposed into Daniels Recital Hall.
The building was acquired by private equity firm KKR in December 2019 at an estimated cost of $440 million.
