The country home of Italians, Ludovica and Roberto Palomba, of the Milan-based architecture firm Palomba Serafini Associati was once an oil mill. The couple decided not to add any new walls to the 17th-century space, opting to keep it as close to the original as possible, which included keeping the stone flooring. The biggest change to the home was the addition of multiple skylights, which opened up the space, giving it an airy, bright quality perfect for an Italian country home . . .
