Callie Hilton, a 5th grader, designed and built her own tiny house out of materials repurposed from her dad’s workshop. The house includes a method to heat water and warm the inside of the home, a rain catchment system, a 5V solar panel to light a single bulb, and a composting toilet. It only weighs 25 lbs, so she can move it around by herself.

What an inspiring young lady!
