“Price for the slot was 5,500$ which for a 17-year old was a pretty big investment.”

He dug the power trench by hand and put in the insulation and drywall with help from his parents. It’s legal as long as he skips the winters. Housing is out of reach for most people his age, and his workaround was a garden shed.
