It is a 226-unit development with senior housing, market-rate apartments, and retail space located near the University of Washington. The development faced challenges during construction but has since achieved high occupancy rates and financial returns. It has also been successful in fostering an intergenerational community through shared spaces and social events for residents of all ages.
