H. Smith.","why_significant":"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.","narrative":"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.","period_of_significance":null,"architect_builder":"Architect unknown; builder W. H.
