Skinny House, Historic residence in Mamaroneck, United States.

The Skinny House is a three-story residence at 175 Grand Street in Mamaroneck built from salvaged materials and only about 10 feet wide. Inside are two bedrooms, a kitchen, a living room, and a bathroom arranged across the levels with multiple windows for light.

Nathan T. Seely built this residence in 1932 during the Great Depression after a neighbor donated a narrow strip of land for construction. The project showed determination and building skill during a time of economic hardship.

The house is a landmark of Black enterprise in Westchester County: Nathan Seely founded Seely Brothers Inc. in 1925 with his brother Willard, hired Italian masons and African-American laborers, and built homes for African-American clients. His great-granddaughter, Dr. Julie Seely, wrote a screenplay titled "Skinny House" in 2011. The house is privately owned and not open to the public.

The Skinny House is privately owned and not open to the public, so it can only be viewed from the street. It stands about 20 feet back from the setback line of neighbouring homes, set on a 12.5-foot-wide lot, and is visible from the New England Thruway (Interstate 95). Look for the three ornate gables and the flowerpot ledge under the second-level window.

Railroad tracks serve as support beams in the basement, showing inventive use of industrial materials for the foundation. Parts of a chicken coop were actually incorporated into the living room construction.
