As a salute to the past and to Earth Lovers, the developers at Three Pillars Group reclaimed a 150-year-old barn siding (made from a combination of cedar and Douglas fir trees) to create a traditional fa‡ade for a modern interior in this Peconic home named Rise. The five-bedroom, six-bath property saves energy with radiant-heat floors, which reduce the temperature loss typically associated with air-infiltration systems, and with a metal standing seam roof, which conserves up to 40 percent of energy costs by reflecting the sun’s rays. The property also uses glass in the kitchen and on the railings, since the material lasts for decades and doesn’t involve hazardous odors or staining (as wood does). Perhaps the most environmentally friendly aspect is the garage: With 1,000 square feet, it can house up to four Smart Cars or countless bamboo bikes. Offered at $2.25 million.
