The name Twinbrook or Twin-Brook came from the four developers, Joseph L. Geeraert, Roland Simmon, Wesley Sauter, and Donald Gingery, who originally established the new subdivision on October 18, 1946.

To meet this need, Twinbrook developers Geeraert and Gingery looked to the planned communities of Levittown, New York and Oak Ridge, Tennessee for guidance and incorporated the ideas of Frank Lloyd Wright's Usonian homes, which were simple and affordable but comfortable and technologically advanced homes.

[3] The first section of Twinbrook to be developed was the area south of Veirs Mill Road, with construction starting shortly after the original 1946 purchase of the property and the first owners taking possession of their home in September 1948.

There were multiple styles of homes in the development, though the most readily identified were the Cape Cod style homes identified as the "Famous Five" in the initial marketing and all featured large picture windows and finished first floors and unfinished second stories, which lowered the price for buyers and allowed them to finish the upstairs space to their own specifications.

The Federal Housing Association removed the language in December 1949 and by the 1950s Twinbrook's racial restrictive covenants had disappeared.

Filling one of the most urgent needs of the new community, an eight-room Twinbrook Elementary School opened in 1952, with an additional 12 classrooms added the following year and more than doubling the capacity to 550 students.

This second center more than doubled the retail space for the community and its opening even featured future United States Vice President Hubert Humphrey.

[12] Though the subdivision came to life at the dawn of the golden age of the automobile, public transit was still an important to help the influx of families get around and to work, which often included commuting into Washington, DC.

The owner to renter ratio has shifted back in favor of owner-occupied homes and the development around the Twinbrook Metro stop is also spurring increased interest in the 60+ year old subdivision.

The major redevelopment taking place at the Twinbrook Metro station will include replacing the large, underutilized parking lots attached to the station and replacing them with Metro parking structures and high-density retail and residential development in the essence a town square.
