Designer John Picard isn’t afraid of getting his hands dirty in the kitchen, or washing the sand off his feet in the bathroom. This ecological pioneer’s half-lot home is designed for maximum efficiency—and comfort. Opening onto the open-plan living and dining rooms, the aluminum Bulthaup System 20 kitchen with its nine-foot-long stainless steel island and Miele appliances has become a focal point of the house. Pressed in one seamless sheet of steel, the island, Picard says with the obvious pride of a satisfied customer, “is an amazing piece of engineering.” Photo by Gregg Segal. Photo by Gregg Segal.
