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.[5] It is the fifth-tallest building in Seattle, and the tallest building completed since 1990.

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 that has yet to open.[6][7] 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.[1]

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.[8]

Design[edit]

To achieve LEED Silver standards, the tower will have a system to capture rainwater for reuse, a 35-foot-tall (11 m) "living wall" where plants grow in a Columbia Street façade, and rooftop solar energy equipment.[5] Plans called for the building to be smallest at its base with each floor a different size.

The glass walls of the building were designed to regulate temperature and energy use by letting in some sun rays and reflecting others. It uses the same glass as the One World Trade Center in New York City.[5] The building features an internal staircase system that encourages walking over elevator use, a design that was requested by F5. The company has 59 meeting rooms and 290 collaboration spaces in the building, as well as an open office floorplan.[9]

The building includes 516,000 square feet (47,900 m2) of office space, which was leased for 14.5 years to F5 Networks for $360 million. The lower 13 floors include a hotel with 189 rooms.[10] The hotel was originally designed and furnished for SLS Hotels, a luxury operator, but the original contract was terminated in 2017.[11][12] Lotte Hotels & Resorts of South Korea bought the rights to the hotel and sanctuary in December 2019 for $175 million with financing from Hana Financial Group.[13][14] Lotte Hotel Seattle, the company's 31st location, is planned to open in September 2020 with 189 rooms on 16 floors.[15]

Construction[edit]

Shoring and excavation began in summer 2008 and was delayed due to economic conditions. Construction re-started in the summer of 2014.[7] During construction, cables and shoring mechanisms left over from the construction of the Columbia Center in the 1980s were discovered, which led developer Daniels Real Estate to file a lawsuit in August 2015 against the owners of the Columbia Center.[16] The building topped-out in July 2016.[17] The building officially finished construction in May 2017.[2]

Incidents[edit]

On September 17, 2016, a construction elevator suddenly dropped multiple floors, injuring one of the three men aboard at the time. The exterior elevator was somewhere between the 33rd and 37th floors when high winds caused a power cord to slip and catch on a fall protection net outrigger.[18]
