F5 Tower

F5 Tower is a 660ft skyscraper that is under construction in Downtown Seattle, Washington. It will consist of 44 floors and be completed in late August or early September 2017. When completed, it will be the fifth-tallest building in Seattle, and the tallest building completed since 1990.The tower will consist of 516,000sqft of office space leased entirely by F5 Networks and a 189-room luxury hotel operated by SBE Entertainment Group. It was designed by Zimmer Gunsul Frasca and is being developed by Daniels Real Estate. Out of all skyscrapers under construction amidst Seattle’s historic construction boom, F5 Tower is the most expensive.The tower is being 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 is being preserved and has since been re-purposed into the Daniels Recital Hall.DesignTo achieve LEED Gold standards, the tower will have a system to capture rainwater for reuse, a 35ft "living wall" where plants grow in a Columbia Street façade, and rooftop solar energy equipment. Plans call for the building to be smallest at its base with each floor a different size.The glass walls of the building are designed to regulate temperature and energy use by letting in some sun rays and reflecting others. It will use the same glass as the One World Trade Center in New York City.
