Levittown, formerly Island Trees, is a hamlet and census-designated place (CDP) in the Town of Hempstead on Long Island, in Nassau County, New York. Levittown is halfway between the villages of Hempstead and Farmingdale.
The building firm, Levitt and Sons, headed by Abraham Levitt and his two sons, William and Alfred, built four planned communities called "Levittown" (in New York, Pennsylvania,New Jersey, and Puerto Rico), but Levittown, New York, was the first. Additionally, Levitt and Sons designs feature prominently in the older portion of Buffalo Grove, Illinois;Vernon Hills, Illinois; Willingboro Township, New Jersey; the Belair section of Bowie, Maryland; and the Greenbriar section of Fairfax, Virginia. The Levitt firm began before World War II, as a builder of custom homes in upper middle-class communities on Long Island. During the war, however, the homebuilding industry languished under a general embargo on private use of scarce raw materials. William "Bill" Levitt served in the Navy, and developed expertise in mass-production building of military housing using uniform and interchangeable parts. During this same period, he was insistent that a postwar building boom would require similar mass-production housing, and was able to purchase options on large swaths of onion and potato fields in undeveloped sections of Long Island.
