Built in 1898 as part of the Masury family waterfront estate.","why_significant":"The nomination argues it is architecturally significant as a distinguished example of turn-of-the-century upper-income estate architecture on Long Island. Its plain shingled exterior contrasts with a lavishly decorated interior that retains a high level of integrity. It is the only surviving building of the estate and recalls the South Shore's opulent estate era.","narrative":"Built in 1898 on Masury Point in Center Moriches, this long, one-story shingled building was the ballroom of a waterfront summer estate planned by the widow of paint manufacturer John Wesley Masury and designed by New York City architect William Lambert. The mansion and support buildings are gone; the mansion was badly damaged in the 1938 hurricane and dismantled. The T-shaped building holds a ballroom, taproom, bowling alley and billiard room. Its exterior is modest, with wood shingles, a broad hip roof and wrap-around porches. Inside, the ballroom has an oval painted dome, a railed mezzanine, paneled walls, parquet flooring and a classically detailed fireplace. The estate hosted frequent social events in the early twentieth century, and dances for servicemen continued into the 1940s. After the estate was subdivided in 1954, the ballroom was sold to a property owners' association, which still maintains it as a clubhouse. It is the last surviving piece of the estate.","period_of_significance":"1800-1899 (specific date 1898)","architect_builder":"William Lambert","architectural_style":"Eclectic style combining Shingle style massing with Colonial Revival detailing","criteria":[],"status_note":"Occupied and in good condition; used as a clubhouse and still owned and maintained by a property owners' association.
