It may incorporate an eighteenth-century house, was enlarged in the nineteenth century and was expanded and restyled in Colonial Revival form in the 1920s.","why_significant":"The house is significant under Criterion C in architecture as a typical Long Island farmhouse enlarged over time, then given a Colonial Revival overlay in the early twentieth century. It reflects the period when wealthy city residents bought old farmhouses and updated them to evoke the colonial past. Documentary proof of an eighteenth-century construction date is lacking.","narrative":"This house on Frost Mill Road in Mill Neck, Nassau County, began as a modest colonial-era farmhouse and grew over two centuries. Records mention a house on the land in 1714, 1741 and 1763, and eighteenth-century framing survives in the attic, though the original builder and construction date are unknown. The property passed from the Wright and Frost families to the Underhills, who held it until 1907. In the nineteenth century it became a five-bay, center-hall house with a lean-to addition. After Katherine Culver Williams bought it in 1927, the house received dormers, a screened sleeping porch, a larger dining room with French doors and a period-style mantel, and an east wing with a modern kitchen. Barns, a henhouse and a shed were built to look colonial. It is valued as an example of a Long Island farmhouse repeatedly enlarged and then restyled in the Colonial Revival manner, with significance dated from about 1890 to 1944.","period_of_significance":"Ca. 1890-1944","architect_builder":null,"architectural_style":"Colonial Revival","criteria":["C"],"status_note":"Listed as a residence; current function is domestic/residence.
