Teenager Austin Hay completed construction on a tiny house with wheels that he had begun during his sophomore year of high school.

The home includes a full kitchen, loft, shower and composting toilet, and is based on plans donated by the Tumbleweed Tiny House Company. The graduating senior wants to add solar panels some day.

He recently held an open house during which his grandfather was moved to tears when asked about his financial outlays that helped Austin finish his tiny dorm on wheels.
