The shed arrived well packed and undamaged: However, in the building if you don't have building skills, you are running the risk of breaking the panels. A set of 6 clamps and some wood from the pallet to create 45 degree angles on the corners and a centre plank running from one wall to the other, stabalise the frames and keep the corners straight. Due to certain foundations it is better to have some bigger screws to hold the frames to prevent stress. I also chaulked the seams to keep it water tight. Over all the value of the shed is good, as I have an 18 foot by 6 feet. It serves my purpose. Thank you for a good product, some tweaking and it would be perfect.
