The Stewart House is a handsome L-shaped residence that retains the characteristics of Greek Revival architecture and features symmetrically placed windows flanked by distinctive pilaster trim. It was constructed in the 1840s by Daniel and Alexander Stewart, who were associated with the Denton Mills, Centreville's famous maker of sleeping garments. Although passing through many hands, the house has remained with Frank Holtom's descendents since 1909 and has carried the name of "Lōnelm Farms" for many years.
