520 Centre Street is a 2 1/2 story, 5 bay, rectangular plan, wood frame, Colonial Revival, residential building. Constructed c. 1920, the hipped roof house is ornamented with a massive center chimney, enclosed pedimented portico with round-arched leaded fanlight, 6/1 windows, and overhanging bracketed eaves. Although altered with synthetic siding, the house retains enough integrity to qualify it as contributing to the historic district.
