Fifteen Twenty-One Second Avenue, Residential skyscraper in downtown Seattle, United States.
Fifteen Twenty-One Second Avenue is a residential tower in downtown Seattle containing 143 condominium units across 32 floors. The 440-foot (134 meter) glass structure allows views of Elliott Bay and Mount Rainier from many of its homes.
The tower was completed in 2008 and marked a shift toward high-end residential development in Seattle's downtown core. Construction finished during a period of economic uncertainty, reflecting bold confidence in the city's residential market.
The tower represents contemporary urban living for Seattle residents seeking downtown locations near water views and mountain horizons. Its design has become part of how locals perceive modern residential architecture in the city.
The building sits within walking distance of restaurants, shops, and public transit in a central neighborhood. Note that this is a private residential building, so only publicly accessible areas can be viewed from outside.
The roof features four vertical glass fins that rise to meet a 40-foot curved mechanical screen at the crown. This distinctive architectural element creates a dramatic silhouette visible from many vantage points around the city.
