Pyramid House - Sunapee Region, NH
2018 EXCELLENCE IN GREEN DESIGNhis new country house sits atop a hill in the Lake Sunapee region of New Hampshire. Three distinct pyramid shaped roofs make this residential project unique while the cedar-shingle siding, and the courtyard in the main foyer maintain the simplicity of traditional country style. Energy-efficiency was an element we incorporated from the initial stages of schematic design. For example, the building envelope consists of 12 inch double wall construction filled with blown cellulose insulation, and the lower sloped metal roofs are filled with close-cell spray foam. In addition, we placed a six-inch under-slab of insulation to retain heat, and the foundation walls are insulated on both the inside and outside. Each of these details allow for a very efficient building, and for the inhabitants to stay warm during the coldest New England winters. Furthermore, the robust envelope makes for a more resilient building overall. The Ground Source system provides the heating and cooling, while a large woodshed provides the necessary space for an abundance of firewood, cut by the owner. A screen porch with a fireplace and removable glass panels allow for year-round use.
Along with a tight building envelope, acoustical considerations were of the utmost importance to our clients. Therefore, aside from the acoustic separated walls, the floors have acoustical channels below the framing, and a layer of concrete above to reduce all noise and vibration transfer between levels.
Thoughtful design, with a consideration to practicality, allows for this building to be used throughout the year, and enjoyed for multiple generations.
