The Inflatable Concrete Houses of Florida

These two historic homes were built by inflating a giant rubber balloon and spraying concrete over it. Once the structure hardened, the balloon was deflated and removed, leaving a permanent shell.

Created using a unique airform method, these houses demonstrate an unusual approach to construction meant to be durable and cheap. By inflating a membrane like a balloon, builders could form seamless, curved concrete walls without traditional framing. Though they look like quirky desert domes, they have stood the test of time in the Florida humidity. It is a fascinating glimpse into mid-century architectural experimentation.
