How do you build a run from 2x4's? I want to make it at least 30ft by 30ft and minimum 4ft tall. I rather it not be taller because there isn't a need and I won't be living in there anyhow! Maximum size would be around 60ft by 40ft, bird/deer netting on top and hardware cloth on all sides. How do I build a door/door way? How do I make the corners strong? Do I make 10ft wall sections and then lift them up in place and screw them into the next? How do you make the walls strong enough to stand and to support a top net? Anything else I should know? I want to make minimal cuts of the 2x4's. I will be using a hand saw most likely, but even if I get a table saw, I'd like it not to have notches and all that fancy stuff. Any pictures on how to do this, with steps?
