Round homes ask us to rethink building conventions. Their curves offer comfort, efficiency, and surprising strength—but they require intentional window design. Whether you’re building in the desert, forest, or city fringe, one of these solutions will fit your climate, materials, and aesthetic.
Some small Binishell prototypes have been built for around US $3,500 using sprayed concrete over an inflatable form. Automatic Construction reports shell costs of roughly $10–$30 per square foot for 100- to 200-square-foot prototypes—far below standard homebuilding prices. The Vienna method is described as “quick and cost-saving” for double-curved shell structures, but specific dollar/€ cost numbers are not given in the available sources.
