The Spencer–Shippee–Lillbridge House, also known as the Crossways Farm and Walnut Brook Farm, is a historic farmstead at 12 Middle Road in East Greenwich, Rhode Island. The main house is a 2+1⁄2-story timber-frame structure, five bays wide and three bays deep, whose construction date is traditionally given as 1772. There is, however, architectural evidence that it may be older. The building has a small 19th century addition, whose purpose was to provide a staircase for hired farmhands to reach the attic, where their living space was. The downstairs spaces have retained much of their original Georgian fabric, although a pantry space has been converted into a modern kitchen. There are five outbuildings on the 1.3-acre (0.53 ha) property, including a 19th-century wagon shed and horse barn. The house, once the centerpiece of a 225-acre (91 ha) farm, was held by members of the interrelated Spencer, Shippee, and Lillbridge families from its inception until 2001.
