Built in 1803, it was designed by Gabriel Manigault to be the home of his brother, and is nationally significant as a well-executed and preserved example of Adam style architecture.

The main facade has a two-story porch across the center three bays, with elaborate doorways on both floors featuring slender pilasters and sidelight windows.

A semicircular stairwell projects from one sidewall, and a bowed porch from the other, giving the house the rough shape of a parallelogram.

The interior features delicately refined woodwork in its fireplace mantels, door and window moulding, and cornices, reflective of the style promoted by Robert Adam, which differentiated the scale of these elements in domestic and civic architecture.

Gabriel Manigault had studied architecture in London before the American Revolutionary War, and was familiar with Robert Adam's design principles.
