Phase 2 of the groundbreaking Grow Community on Bainbridge Island is underway and it includes a mix of multifamily and townhome dwellings. Situated around a large open space studded with trees and wandering paths, the first four completed buildings of Phase 2 offer residents a direct connection to nature. And yet the development is only a short walk to the town center and coastline.

The eight townhomes in Building C feature a striking exterior of wood, steel, and glass. Behind the rustic cladding is a modern rainscreen with a liquid-applied weather barrier to properly manage water. The building envelope is also wrapped in an inch of Roxul mineral wool insulation for thermal and moisture control. Two stories in height, the townhomes sit above a subgrade parking garage to ensure the site focus on walkability. Each home has a front porch and back patio to encourage connection with the community. The interior design places emphasis on openness, height, and natural light. 

Sustainability is a focus in the Grow Community. Each unit in Building C utilizes a Heat Recovery Ventilator (HRV) for continuous fresh air, a ducted mini-split heating and cooling system, and a super-efficient heat pump water heater located in the garage. Onsite stormwater is managed by numerous rain gardens, swales, and "creeks" to slow and infiltrate rainwater. Interior finishes include No Added Urea Formaldehyde (NAUF) cabinets, bamboo flooring, low VOC paints, and solid fir millwork.
Beyond the technicalities of the buildings, Grow Community is designed to cultivate a healthy, happy, and sustainable community for all ages. The physical space provides a vehicle for residents to achieve a simpler and more mindful lifestyle with a lower impact on the environment.
