All of Onx’s homes get built with precast concrete walls and factory-made bathroom pods, a modular system that the company claims allows it to complete a home in 30 days.

Grandio created the Hüga, a $75,000 prefab concrete tiny home that is both weather and bulletproof. Tiny homes have boomed in popularity this past year, and the Hüga is no exception.
