The Modern Portland Residence design is a balance of sustainability, the client's needs, budget, and context. In order to save on precious floor area, energy use, and money, an efficient floor plan was developed exploring bold moves like eliminating the dining room and creating a built in bench with a dining table placed in the living area. Cellar Ridge created Portland's first 50/10 residential project. The goal of Cellar Ridge and the homeowners was to balance a budget with sustainability. The answer was to build the home with 50 percent more energy efficient than code at just 10 percent greater cost. The resulting home is certified Net Zero and Earth Advantage Platinum. The modern home includes an extensive air sealing package, a recycled metal roof prepped for a future solar array, a heat recover ventilator and VOC-free interior finishes for cleaner indoor air quality. The project resulted in an 1800-square-foot passive solar house with an open-concept living area that overlooks the backyard. "Being first-time homewoners, there's always the 'woulda, coulda shouldas,'" said the homeowner ((ROYAPET)), "but we're very happy with the house that we have."
