Phelps and now used as the clubhouse of a private club.","why_significant":"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.","narrative":"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.","period_of_significance":"19th Century (specific date 1870)","architect_builder":"Architect Isaac G.
