Perfect size for the space I have available! One person assembled in 3 1/2hr, I was amazed!  The only thing not included was screen to cover the vents from inside. I have lots of critters & birds by the river and don't want them getting inside.  I used a 10"x10" piece of sheet rock patch and has adhesive on the back. Then added heavy duty duct tape around edges to make sure it stayed in place.  Now it's ready for 2 people to move to a slab on the other side of wall.
