The inspiration for this house came from the site’s superlative view of Edgartown Great Pond. House, guest house, garage, parking, swimming pool, several terraces and lawns were arranged in a gentle crescent that focuses attention on the unique landscape. Warding off environmental damage, however, was a challenge. Red cedar shingles with stainless steel nails extend the life of the roof, while an extensive dehumidification and insulation system keeps moisture at bay.
