Charles A. Platt designed it in 1906 for Christopher Temple Emmet and Alida Chanler Emmet.","why_significant":"The house is presented as an intact representative example of the Stony Brook Harbor estate type and as a fine work of architect Charles A. Platt in the Colonial Revival style. It is also tied to the extended Smith and Emmet families, who shaped country house development around the harbor in the early twentieth century. It retains its harbor setting and some original specimen plantings despite the loss of most of its acreage.","narrative":"Built in 1906 at Head of the Harbor on Long Island, The Mallows is a stucco Colonial Revival country house designed by Charles A. Platt for Christopher Temple Emmet and Alida Chanler Emmet. It is a two-story, seven-bay rectangular block with a gabled roof, pedimented dormers, large chimneys and Doric wooden detailing. A monumental two-story porch on the west end looks out toward Stony Brook Harbor. Inside, a curving staircase, a dining room frieze by muralist Robert Chanler and twenty-eight rooms reflect its role as a large entertaining estate. The property was once over 150 acres, but now only 4.1 acres remain, with lawns, tennis courts and old plantings such as English holly and smoketree. It was listed for its architecture as a fine example of Platt's Colonial Revival work, and for its links to the Smith and Emmet families who built summer estates around the harbor around the turn of the twentieth century.","period_of_significance":"1906","architect_builder":"Charles A.
