Whether you are planning a major renovation or shopping for a new table, the granola years of environmentally correct design are over. Now stylish options can please the eye and soothe the conscience. Sleek furniture made from salvaged wood and harvestable materials are a natural complement to bamboo and cork floors, which have a graphic look and a swank midcentury vibe. Dazzling tiles made from recycled glass and metal add a shot of luxury and color to a kitchen backsplash or shower wall. So go ahead and save the planet, but remember: Eco-friendly doesn't always mean economical.
