This two story Nantucket style home has 4000 sf of finished living area, and was designed through the collaboration of the owner with a plan designer, with a few of our suggestions thrown in for good measure. The windy waterfront location on Middle River required some extra thought about insulation and air infiltration. In the crawlspace ceiling we installed closed cell spray foam insulation that not only provided a high level of insulation, but also sealed out air infiltration and keeps the floor toasty warm. On the exterior walls, we used a combination of Tyvek air infiltration wrap and a double layer of sheathing on the 2×6 exterior walls. The outer layer of sheathing is insulating ½” urethane foam, and the joints are staggered with the structural wood sheathing under it, effectively sealing out air infiltration through the walls. To further reduce the carbon footprint of this home, a geothermal heating and cooling system and tankless gas hot water heater were installed, at a much reduced cost thanks to the tax credits provided by our Uncle Sam. With an eye to the future, and aging in place, we installed a shaft and rough ins for an elevator as well as 3’ wide doorways and blocking for grab bars in the bathrooms. As is usually the case, we had to demolish an existing shore shack to make room for the new home. Being the green builders that we are, we were able to use the crushed block as a base for the new driveway, and we recycled the concrete from the demolition. We also protected and saved the existing mature trees on the lot during construction. The beautiful setting for this home is enough to make the owners feel that they are on a permanent vacation, and “Gone Fishing” will be the order of the day.
