Roofing: Chicago resident Marie Delgavio owns an industrial-style loft in the heart of the city’s West Loop neighborhood. What sets her residence apart from others on the block is its private rooftop, which is a “highly sought-after home amenity for city dwellers like me,” Delgavio says. While incredible even in its bare form, Delgavio saw her underutilized rooftop as an opportunity to design a functional and inviting outdoor living space where she could relax, entertain, cook and tend to her container garden. “Living space is limited in condominiums and homes in the city, so it’s important to take advantage of any usable outdoor space,” she adds.
