Why it's listed

Built in 1870 at 191 Court Street in Binghamton, this two-story brick mansion was commissioned by Sherman D. Phelps, a former mayor, at a cost of $100,000. Isaac G. Perry, later chief architect of the State Capitol in Albany, designed it, and John Stuart Wells served as builder. The house is five bays wide, with an apsidal solarium on the east side, granite quoins and segmental keystones over the windows. A third floor and high mansard roof were removed in 1941, and an auditorium was added at the rear in 1905, when a private club bought the property. Its interiors are the main distinction: imported marble, decorative tiles, custom chandeliers, and carefully chosen woods including maple, walnut and oak in the principal rooms. A hand-carved black walnut staircase, made by Orville F. Roth for $10,000, rises from the central hall. An old iron fence by the Titchener Iron Works marks the Court Street entrance.

Significance in brief: The nomination presents the mansion as an outstanding example of an architect's imagination and a craftsman's skill, especially in its interiors of rare woods, marble and glass. It was designed by Isaac G. Perry, a nationally recognized architect who became chief architect of the State Capitol in Albany. It also reflects the elegance of early Binghamton's finest residential district.

What listing means for this property

National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).

Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.

General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
