Los Angeles has been experiencing a housing shortage for decades—with many of the new residential structures being built offering a larger proportion of luxury housing than affordable units. And that shortage has worsened in the wake of the January 2025 wildfires that wiped out nearly the entire communities of Altadena and the Pacific Palisades.
There was a severe need for housing in the U.S. in the 1940s, too—with building materials being rationed for the war effort and then all those soldiers coming home after World War II and starting families with much enthusiasm (launching the "baby boom" generation).
Back during the war, one answer to that housing shortage was offered by architect Wallace Neff: the Airform house, which could be constructed in just two days.
All it took was to cover a giant balloon (made of rubberized nylon) with chicken wire and spray it with concrete (a.k.a. gunite). Deflate the balloon and boom, you've got a house—or, as it was called, a "Bubble House."
Despite their speed and affordability, fewer than 3000 Bubble Houses (or "Balloon Houses") were built in this country. Only one of them remains, built at a cost of $16,000—and it just went on the market for a whopping $1.85 million.
