unless you built it on a farm wagon chassis and planning to move it with a tractor, you have to build with weight in mind. Being in southern climate or building for 3 seasons use only would help a lot.I agree with @kwhites634 about weight. I have a relatively small coop, about 4ftX5ft and only 3ft tall at the highest point. Even on wheels, there's no way I could easily move it by hand. Coops get heavy fast.
