Designed as an innovative “Smart Green” affordable housing community for University of Washington and Seattle Children’s Hospital employees, Bridges@11th, a 139,938 sf development blends live and work spaces for busy working families.

Amenities for the 184-unit housing complex include rooftop gardens and social rooms, pea patches and pet-walking areas, exercise facilities, a Wi-Fi café for residents and parking garage. The perimeter of all three Bridges@11th buildings support an active pedestrian lifestyle and encourages residents to connect and build community with ground-level housing, live-work areas, retail, a bike club and bike storage.

Glumac provided MEP engineering design assist, energy analysis, and building commissioning services. Our team collaborated with the architect on several sustainable design features, including a decoupled system using Heat Recovery Ventilators as a dedicated outside air system (DOAS) in conjunction with high efficiency Heat Pumps to condition air in many common areas such as the lobby and fitness center.
