After much research, I ordered this shed to replace a metal shed which was 45 years old. I had help from a friend who was not very good at following instruction books. Every time he worked alone, he made mistakes. The instructions were largely line drawings, needed to be followed exactly, and the parts were well indicated. Looking back, I should have color-coded them to make them easier to follow.
The quality was outstanding, with metal reinforcement throughout. All the parts were carefully coded and in separate bags and bundles. The shed arrived in 2 boxes on a single double sized pallet on my driveway. It could not be moved without a forklift so I opened the boxes in place, then carried the pieces to my backyard.
A level base is critical for the pieces to fit. The floor has spots to anchor it to the base-my base was the concrete slab from the old shed. It took both of us on ladders to attach the roof and slide in the top sections of the walls.
By the way, I am 80 and my helper is 65.
