The Insignia Towers, also known as 2301 6th Avenue and formerly as the Embassy Development Project, are a pair of 41-story residential skyscrapers in the Denny Regrade neighborhood of Seattle, Washington. The buildings are mainly residential condominiums with lower-level shops. The project was originally approved in 2007, but was placed on hold during the late-2000s recession; it was revived in 2012 and began construction that year. The South Tower was completed in 2015, and the North Tower was completed in 2016. The two towers have 707 residential units and 1,000 parking spaces.
