This inventive, central-hall house is a magnificent example of a trust-lot mansion. It was erected for Aaron Champion, a banker from Massachusetts, by Hermitage Plantation owner Henry McAlpin, whose son married Champion’s daughter and thus inherited the house. The design, commonly attributed to Cluskey, features a colossal Greek Revival portico with four Tower of the Winds columns standing in antis between channeled corner piers. Set back behind an elegant iron fence, the house rests on a partially raised basement and is accessed by a double curved stair. Classicizing details abound in the interior, which features an oval oculus between the first- and second-floor hallways, aligned with a rectangular opening and monitor above to facilitate convection ventilation. First-floor rooms were lit by grand gasoliers made by Cornelius and Company in Philadelphia. The 1895 modifications added a third floor, built into a mansard roof, and relocated the main stair to the rear where the double gallery was filled and fronted by an exuberantly swooping iron and copper canopy. The Society of the Cincinnati took possession of the house in 1988 and commissioned the 1995 restoration, carried out by Sterling Builders and Restoration, which uncovered the magnificent faux bois (false wood) paintings on the walls and ceiling of the dining room. The carriage house at the back of the lot is a reconstruction by the Spriggs Group (1999–2002), placed atop the original building’s foundations, and the modern garden was designed by John F. McEllen.
