Designed by Philadelphia architect Horace Trumbauer, the stable and the adjacent mansion remain fine example of Tudor revival architecture with half-timbering, stucco wall cladding and clay-tiled-roofs—an academic style based upon late Medieval English prototypes that was common among suburban domestic architecture in the United States in the early-20th-Century.

[2] Although still uncommon prior to World War I, Tudor Revival became an immensely popular style during the 1920s and 1930s.

In 2002, the Vandalia Heritage Foundation[3] partnered with Friends of High Gate, to ensure continued preservation and restoration of the Carriage House and Gardens.

Vandalia Heritage Foundation will enhance use of the Carriage House and Gardens and facilitate restoration of the second floor of the building, to be utilized for office space.

Upon completion of the second-floor restoration, Vandalia will truly be able to "Keep the Gates Open," preserving a significant National Historic Landmark in West Virginia's history, and an important moment in the local history of Fairmont.
