Halsey Estate-Tallwood
Why it's listed
Tallwood is a large shingled estate house built around 1925 on 12.8 wooded acres along Sweet Hollow Road in West Hills, Huntington. Its 22-bay, symmetrical form has a two-and-a-half-story gambrel-roofed central block with pedimented dormers, six-over-six windows, a modillioned cornice and a columned entrance porch, flanked by gable and gambrel wings. The central block replicates the Prince House, built about 1750 in Flushing and demolished in the 1950s. Richard Townley Haines Halsey, an art critic, antiquarian, author and collector of early Americana, had it built as a personal retreat. He later served as curator of the American Wing at the Metropolitan Museum until his death in 1942. Halsey added the flanking wings for extra rooms in the Colonial Revival manner. Inside are Adamesque moldings, plasterwork and marble and wooden mantels. Since the 1970s the property has housed a day camp with playground, mini golf and other non-contributing additions, yet the main house and its lawns remain largely intact. It stands as one of Huntington's few unaltered early twentieth-century estates.
Significance in brief: The nomination argues that the house is a distinctive early twentieth-century Colonial Revival estate and an accurate replica of the circa 1750 Prince House in Flushing, which was demolished in the 1950s. It is also tied to Halsey, an art critic, antiquarian and first curator of the American Wing at the Metropolitan Museum. It is one of the few unaltered estates left in Huntington, reflecting the town's early twentieth-century growth.

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.
