Architects Joseph Tanney and Robert Luntz of Manhattan-based firm Resolution: 4 designed this prefabricated, modular home with two green roofs on Fishers Island, New York. The landscape architects at Reed Hilderbrand planted sedge grass on one of the rooftops to reflect the texture of the surrounding meadow. The second green roof was planted with sedum and plays host to one of the family’s favorite spots: a hammock.
