Union Square (Seattle)
Union Square is a skyscraper complex at Sixth Avenue between Union and University Streets in Downtown Seattle, Washington, adjacent to Freeway Park. It consists of two skyscrapers built in the 1980s and primarily used for office space. The entire complex features a 1,100-stall parking garage, a courtyard, a retail plaza spanning three stories and an underground pedestrian concourse that connects with the Fifth Avenue Theater and Rainier Square. Both structures were awarded LEED certification in 2009 and eventually received LEED Platinum certification 6 years later as a result of reduced annual energy consumption by 40 percent through recent renovations. The entire complex is currently managed by Washington Holdings, a real estate firm also known as Union Square LLC which is based in Seattle.
