Why it's listed

Perched on a hilltop crest above Walnut Neck in Asharoken, on Long Island's North Shore, this large Tudor-style mansion was completed in 1902 to designs by architect Harry E. Donnell. Oakley R. DeLamater built it as a wedding gift for his wife, Elizabeth Hasbrouk, and the family used it as a summer residence. The house rises three stories above a brick basement, with clear cypress trim, hardwood floors, cedar shake roofing, Tudor gables, five fireplaces, eight bedrooms and a separate servants' wing. Water can be seen on three sides. Oakley was the son of Cornelius DeLamater, whose iron works helped build the Civil War ironclad Monitor, and the house is one of two DeLamater family homes in the area. The family lost the estate during the Depression, and later owners subdivided the land and made repairs and restorations. A restoration finished in 2007 retained original plaster, doors, glass and hardware where possible.

Significance in brief: The house was built as a wedding gift for Elizabeth Hasbrouk DeLamater on land belonging to the DeLamater family, whose fortune came from the DeLamater Iron Works and its role in building the Civil War ironclad Monitor. It is one of two DeLamater family houses in the area. The documents state it appears almost as built and has been restored. The supplied pages do not include the form's formal significance section.

What listing means for this property

National Register listing is honorary: it recognises significance and does not restrict what a private owner may do without federal money or permits.
