Success! We removed the plywood around the playhouse base and tried pulling the playhouse down. Nothing. It’s an odd combination of flimsy and sturdy, but sturdy won out. Scott wrapped a chain around the front 4×4’s and cut through them. For safety, he tacked in two non-cut 4x4s to act as braces while he cut the structure. Pulled again and nothing — those two braces held the entire building.
Then the took other dimensional lumbar and threw it like a javelin at the two braces. A single brace still held the whole building, but after the second brace was removed … we finally have success. It came down in one piece — there are a few dings and the front porch was damaged. But we’ve got a little building at ground level. Now to flip it, clean it up, and get the chickens moved in.
