New Hampshire Home > This open, energy-efficient house for a busy family of five takes full advantage of a spectacular waterfront site in Southern New Hampshire. The plan is tailored closely to the allowable shorefront setbacks, nestling the house into the landscape. The open-plan main level does not compromise the integrity of the individual living, dining, and kitchen spaces. The lower level children's suite has access to the outside from a central playroom. The design captures water views on three sides, and every living space receives ample natural light. And with a HERS rating of 26, the house is a model of energy efficiency, demonstrating that superior design and environmental responsibility work well together.
