Why it's listed

Built in 1884, this two-story clapboard house sits on a large triangular lot where Glen, Roslyn and 15th Avenues meet in the center of Sea Cliff. It is a Queen Anne style residence with a slate cross-gable roof and a three-story square tower with a pyramidal hipped roof. Alternating bands of fishscale and standard shingles decorate the tower and gable ends, and a wraparound porch has turned posts, spindle and ball detail, and a denticulated cornice. Three corbelled brick chimneys rise above the roofline. Inside, black marble and brick fireplaces, a skylight and paneled woodwork remain. The house was built by W. H. Smith, a prominent local builder, during the years when Sea Cliff was changing from a camp meeting ground into a fashionable seaside resort. It is described as a particularly large summer residence of that era, and its high-quality Victorian ornament recalls the period of the village's most extensive growth. The exterior is reported unaltered since construction.

Significance in brief: The house is presented as a distinguished example of late nineteenth century resort architecture in Sea Cliff. It keeps a high level of integrity and shows fine Victorian-era detail, including a corner tower, wraparound porch and decorative shingling. It also reflects Sea Cliff's mid-1880s shift from a rustic camp meeting ground to a fashionable summer resort.

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.
