F5 Tower, Modern skyscraper in downtown Seattle, United States
The F5 Tower is a modern skyscraper in downtown Seattle with 44 floors above ground and 9 basement levels, featuring floor-to-ceiling windows throughout. The building houses office spaces and a 189-room hotel, with a glass passageway connecting to adjacent historic structures.
Construction of the tower began in 2014 and was completed in May 2017, marking a new phase in Seattle's downtown development. The project represented a major shift toward integrating modern office and hospitality spaces within the historic core.
The tower connects to neighboring historic buildings through a glass passageway that links it with the First United Methodist Church and the Rainier Club. This design shows how the city blends development with preservation of its heritage structures.
The building contains 17 elevators for efficient movement between floors, serving visitors with smooth access throughout the structure. The combination of office and hotel functions provides diverse amenities for people moving through the space.
The building features an advanced mega-brace structural system designed to withstand severe seismic activity. This engineering approach makes the structure exceptionally resilient against major earthquakes that could occur in the region.
