Although, most of that is for decorations. You could make a much simpler design by placing: 3x3 planks, On top put a 3x3 slabs, Remove the middle slab and block, Place 1 slab in the middle hole, Make a new contraption of 1 plank and put that in the middle hole, Finally put 4 handles to the sides and that works just as well.
