It was designed by architect Isaac H. Green, Jr.","why_significant":"The nomination argues the house is a distinctive, intact example of the Stony Brook Harbor estate type and an important work of regional architect Isaac H. Green, Jr. It shows his shift from informal Shingle Style to a more formal Colonial Revival and Neoclassical manner. It is also tied to the Smith family circle and the social history of the harbor's summer estates.","narrative":"Built in 1904 at the end of Stillwater Road in Nissequogue, this Neoclassical country house was the centerpiece of a large estate on Stony Brook Harbor. Subdivision has reduced the property to about six acres, but the house and a former carriage house remain. The water-facing east side has a two-story portico with four Ionic columns, a pediment and a balcony, while the west side has a porte-cochere marking the entrance. Inside, fifteen rooms are arranged around a grand central hall. Isaac H. Green, Jr., a leading Long Island architect, designed it for James W. Phyfe, a New York City merchant who married into the local Smith family. Compared with Green's earlier Shingle Style work nearby, the house shows a more formal Colonial Revival approach. It retains the features of the harbor estate type, including a water view, broad porches and a service wing. Later uses included a summer camp and a rental to Gloria Morgan Vanderbilt in 1925.","period_of_significance":"1904","architect_builder":"Isaac H.
