WELCH HOUSE

North Andover   This dramatic and lavish 7,000 sf, five-bedroom house with supplemental workshop/apartment and indoor swimming pool is the first in New England to be built out of aerated concrete block, a super-insulating masonry system pioneered in Germany.  Sited on a rocky outcropping, the house’s orientation and spaces take advantage of passive solar design as well as dramatic views. The house features many cutting-edge energy efficient technologies.
