FRANCONIA MOUNTAIN HOUSE: Envisioned as a retreat for family and friends, this energy-sensitive home is a weekend destination for a young Boston family that wanted to be close the mountains for skiing and hiking. It’s a clean-lined interpretation of rural New Hampshire houses with a combination of board and batten and clapboard siding. There’s a zinc roof, appealing wraparound screened-in porch and a flowing, open floorplan that’s great for entertaining and relaxing as a family.
