It shows hallmarks of the American Queen Anne style, including asymmetrical massing, a tower, varied roofs, verandahs and a porte-cochère. It is also distinctive within the community of Little Neck.","narrative":"Built in 1897 for Charles Van Iderstine, a wealthy businessman and civic leader, this large residence sits on a one-and-one-half-acre plot at the end of Idle Day Drive in Little Neck, overlooking Northport Harbor. It is a two-and-one-half story house clad in clapboard, shingle and shiplap, with multiple wings, cross-gables, a varied gable roof and a three-story octagonal tower with a bell roof. A wrap-around porch on paired Doric columns forms a porte-cochère, and a Palladian stained-glass window lights the stairwell. The house replaced an eighteenth-century homestead lost to fire. It is listed as a representative example of the large mansions built along Huntington's North Shore between 1880 and 1920, and it shows the asymmetry, varied materials and decorative detail of the American Queen Anne style. Although the surrounding estate setting has been lost to new construction and the original outbuildings have been altered, the house remains virtually unaltered and keeps a treed landscape. A c. 1950 garage is non-contributing.","period_of_significance":null,"architect_builder":"Architect unknown; builder unknown, built for Charles Van Iderstine","architectural_style":"American Queen Anne","criteria":[],"status_note":"Private residence in excellent condition, still used as a residence; no threats known.
