Shelter Island Heights in total was a planned development by Copeland. The houses were designed in classic American styles: Stick-Eastlake, Queen Anne Style, and Colonial Revival. During the eight years from 1872 to 1880, when camp meetings were held here, about 70 summer cottages were built in the Heights. By 1890 the district was well-defined architecturally; the residences have not changed much since then. Shelter Island Heights was listed in 1993 as an Historical District on both the NRHP and the New York State Register of Historic Places.
