A new book on the work of the Levitts – Perfect Communities: Levitt, Levittown, and the Dream of White Suburbia – includes this section about developers building at scale prior to the Second World War:

The company had averaged more than two hundred houses per year at a time when just six firms nationwide were constructing as many as twenty-five homes annually in Levitt’s price range. Eighty-six percent of pre-war builders put up two or fewer houses a year, and 60 percent built only one. In 1947, the editors of Fortune magazine called homebuilding “The Industry Capitalism Forgot.” (17)

This is an important feature of postwar suburbia: the construction of single-family homes happened at a scale unknown in previous eras. Before then, many builders built few homes. It took time to put together a block. Neighborhoods and communities grew more slowly. After the war, subdivisions and communities with thousands of residents could emerge within a few years. Fields or woods could be turned into flat land for building quickly. Housing frames went up, the trades came through and did their parts, people moved into completed homes.

The scale and efficiency is hard to compare between these two eras. It is like two completely different processes. The Levitt company argued the new approach allowed them to get needed homes into the hands of people, particularly veterans (but not Black residents), at an affordable price point. Critics said the process led to conformity and a lack of true community. Either way, new communities quickly developed and the processes were adopted by other builders and developers.
