393 Irving Avenue is a 1 1/2 story, 3 bay, rectangular plan, wood frame and stone veneer, former carriage house. (The original, c. 1900, estate house was on the corner of Centre Street and Irving Avenue, and belonged to George Enger.) The hipped roof carriage house features cross gables, end chimneys, a pedimented portico and a cupola. Although it was converted to residential use, and had stone veneer applied to its facade, the carriage house still contributes to the district because of its age and original use.
