Skinny House (Mamaroneck, New York)
The Skinny House in Mamaroneck, New York, was built in 1932 by African-American carpenter and building contractor Nathan Thomas Seely on an extremely narrow lot of donated land after he lost his home to foreclosure and his company to bankruptcy during the early years of the Great Depression. The 10 feet (3.0 m) wide house has 3 stories and was built on a 12.5 feet (3.8 m) wide plot of land sold to him by his neighbor, to whom he had earlier sold a larger plot of land.
