Overbuilding with heavy wood and building inside a structure with no door wide enough to remove the finished product happened with my first stereo cabinet, in around 1980.
I put great thought into weight vs strength. My coop is not overbuilt. I think I will add some 1x2 rafters - to provide support to the roof but keep weight down. up until I added the first roof panel, I could still lift it and move it by myself small distances (like inches). I used a leftover piece of 1 1/4" subflooring 4ft by4ft, cut in half for the floor, with lighter plywood over a 2x4 brace in the center, allowing 1/2 inch drains on either side of the plywood for major cleanups. 3/8 inch plywood for the sides because of weight again. Strong enough, but not as heavy as 1/2 inch. I won't touch particle board for anything. Stuff weighs a ton and has no structural integrity if it gets damp.
Now my run is overbuilt. And there is zero clearance between peak of roof on chicken house and the center beam supporting the chickenwire on top of the run. But I did want it solid so I can attach good fencing, and I do have hawks and vultures and other flying critters around.
But I'm still not moving my coop. At least not without a LOT of help.
