I frame my entire 10 x 16 shed in this video, including my loft and the barn style roof. I did this entire framing project super cheap, saving money on all the lumber by buying cull wood and using free wood from Facebook marketplace for everything I didn't need to buy new. I share how I framed my windows, door and how I got the building plumb and square.
