[2] Architect John A. Kay designed the Hillsborough Military Academy barracks building and commandant's house.

Edmund Strudwick was the doctor for the Hillsborough Military Academy in the 1860s and cared for soldiers wounded in the Civil War at his home nearby.

[3] The commandant's house is a two-story, roughly square, castellated brick building in the Gothic Revival style.

This last reincarnation of the Military Academy was a failure and General Colston relocated to Wilmington, North Carolina in 1868.

The headquarters building became part of the National Register of Historic Places in 1972 and became a private residence known as the "Commandant’s House" while the academy's chapel remains in use as a parish of The United Episcopal Church of North America.
