Twin Oaks, built in 1888 by Francis Allen, is one of the earliest extant examples of Georgian Revival architecture in this country, and is an excellent and notable example of this style. It is is the only remaining example of a New England frame summer house in DC. Twin Oaks was built by Gardiner Greene Hubbard, who made a significant contribution to the development of Washington and the United States through his establishment of the National Geographic Society, as well as his financial support of his son-in-law Alexander Graham Bell, which led to the invention and widespread distribution of the telephone.
Twin Oaks is an estate consisting of 17 acres of rolling lawn and wooded areas, a large frame summer house, and several smaller dwellings. The driveway winds up the hill to the west of the house affording views across the gently sloping lawn to Hubbard's summer home, which has a commanding presence astride the top of the hill.
