[7] The mansion was designed by the architectural firm of Hornblower and Marshall in an early eclectic beaux arts style[2] to serve as the home of George S.

It is constructed of red brick and pink granite with a colonnaded entrance porch with balustraded deck,[8] and a tiled, hipped roof.

In 1901, Fraser's widow sold the mansion to Pennsylvania Congressman Joseph Earlston Thropp, where he took up residence beginning on March 3, 1901.

In 1905, architects Totten and Rogers designed a terrace with an entrance to the house near the oriel window, and also redesigned the garden wall.

In 1982, following a $3 million restoration/renovation,[3] the Fourways fine dining restaurant on the first floor and the Bermuda Bar and Grill below it were opened.

[10] The Fourways served Continental European and American dishes under the leadership of chef Jacques Barre.

[10] Another Bermudian tradition, Bermuda fish chowder with Outerbridge's Original Sherry Peppers Sauce was always on the menu.

While the proposed design for the building was approved by the D.C. Office of Planning and the Historic Preservation Review Board, and the Department of Public Works had determined that the plans, which would have included underground parking for both the apartments and the restaurant, would not cause an increase in parking or traffic problems in the area, the community opposed the building's construction.

Nearby resident Duff Gilfont described the proposed apartment building as "such a blight to this area," and that "there would have been so many people inconvenienced by it.

[12] Following $1 million in renovations,[4] the building was dedicated as the new Founding Church of Scientology on October 21, 1995, by Religious Technology Center chairman David Miscavige.

[14] The Founding Church of Scientology relocated from the Fraser Mansion to the nearby Embassy Building on 16th Street NW on October 31, 2009.
