Lookout House

Capping a hill with views of distant Long Island and the Sound, this pyramid house in Fairfield County, Connecticut, was renovated to erase the aging, brown vestiges of the 1979 original. A new arm stretches to the east, housing the master bedroom suite and family room on the lower pool level. A sustainable project, this house integrates geothermal heating and cooling systems, renewable materials like bamboo floors and eco-friendly paints and finishes.
