I built this cabin completely by myself: poured piles, assembled and poured Arxx styrofoam form foundation, framing, sheeting, insulation, drywall, flooring, shingling, deck, stairs, made my own raised panel pine cabinets, etc - the only thing I didn't do is sprayfoam the attic. This was the first time I ever built a year round dwelling and by all accounts it was a compete success. I bought my first Ryobi (12v cordless) when I started this project and it was a key tool that I used throughout the build. I have since purchased almost all the Ryobi One 18v Lithium tools available as well as several Ryobi corded tools. I have always been impressed by the quality and value of Ryobi. I don't go anywhere without my Ryobi's.
