The 1,775 SF home is a great reminder that strawbale walls can be finished with siding (instead of the typical lime plaster). The 4 bedroom, 2 bathroom house stays toasty in the coldest New Hampshire winters because of passive solar principles, plus a super efficient wood-fired water heater that warms all the floors. Since everything is so energy efficient, the water heater also warms up the attached 740 SF healing studio with a full bath and kitchenette.
