Stratus, Residential tower in Denny Triangle, Seattle, US

Stratus is a 43-story residential high-rise in Seattle's Denny Triangle, completed in 2017 with 396 apartments and ground-floor retail space. Designed by Weber Thompson, it stands across the street from Cirrus, another GID-developed apartment building that opened in 2015 and shares its cloud-type naming theme.

GID Development Group bought the 9th and Lenora site from Cornish College of the Arts in 2014 for $16 million. The lot had previously held a rental car facility. Seattle's Department of Planning and Development approved a 41-story, 430-unit proposal in March 2015; construction began that year and the 43-story building opened in late 2017.

Stratus and its neighbor Cirrus, opened in 2015, were both designed by Weber Thompson and developed by GID; each takes its name from a cloud type, stratus and cirrus. The pairing is visible on the block, where the two towers face each other across the street.

Stratus occupies the block at 9th Avenue and Lenora Street, across from Cirrus. The building has ground-floor retail space, and the adjacent Urban Triangle Park, opened in September 2019, offers an open lawn; a playground structure is planned for the future.

The adjacent Urban Triangle Park opened in 2019 with an open lawn area next to the tower. The park was designed with space reserved for future playground installations, making it an evolving community space.
