483 South Orange Avenue is a 2 1/2 story, 2 bay, irregular plan, wood frame, Gothic Revival-influenced, former residential building. Constructed c. 1880, the intersecting gable-roofed house features 4/4 windows, and a patterned slate-clad roof with clipped gables. Although altered with aluminum siding, the building retains enough integrity to contribute to the historic district. The building is now an engineer’s office.
