366 Hartford Road is a 2 1/2 story, 5 bay, rectangular plan, Colonial Revival, wood frame, residential building. Built c. 1885, the clapboard-clad house features a hipped roof with gabled dormers and a 2 story semi-circular bay dominating the facade. Additional architectural details include brick chimneys, cornice-line modillions, and unique groupings of multiple windows, including lancet-arched upper sash. The house was built by W. F. Havemeyer. By 1904, it was owned by F. W. Horn. Although the entrance doors and some of the windows are replacements, the house has retained enough integrity to be considered contributing to the historic district.
