The basic dimensions are 96" Long - the length of the pressure treated 2X4's. The width is 32" - the third 2X4 cut into three pieces which are the perpendicular stringers on the bottom. I am going to try to make up some plans with all the wood dimensions so a person can prefab it and just nail it togather. I will have all the materials listed so a person can go to the store and see exactly what the end cost will be.
