Traditional Decor Green design can be beautiful, and designers Vasi Ypsilanti and Margreet Cevasco proved the point when they chose earth-friendly products for a showhouse in Long Island, New York. "You don't have to compromise on quality and good design because a product is green," Vasi says. Even if only a handful of products in a building project are from sustainable sources that's a start, she adds. "If 70 percent of the products are green, what a difference that makes in how you live and in what manufacturers produce." Vasi and Margreet designed the kitchen, a wine room, and a breakfast room in a designer showhouse at Caumsett State Historic Park in Long Island.
