In this build I take you from a bare 20-foot trailer to a finished tiny home, step by step, the same way I actually do these projects in the real world. I’m talking framing, sheathing, windows and doors, roofing, siding, and then all the inside work—floors, shower, plumbing, HVAC, and the final details that make it feel like a real home instead of a jobsite. The whole thing took about three and a half months, and I walk through the process in the order that keeps you moving without painting yourself into a corner later. I also call out the products and systems I used along the way—stuff like the Flooret flooring, the Schluter shower setup with a custom base/niche, a mini split for heating and cooling, water filtration, and safety items like a fire alarm. If you’re planning your own tiny home build, the big takeaway is to treat it like a full-size house: build it weather-tight first, then work your way inward, and don’t cheap out on the parts that are a nightmare to redo once everything’s finished.
