Hoping to build a new shed next year. At the moment I am saving up. Plan is to hopefully go 12 x 12 with a 20deg pitch. With 3.6m walls my peak will be 5.78m high. Hoping to work out the most cost effective and if I can trim my walls, because I don't need this much height I will. Plan is to sit the hoist in the middle bay to get max height. I need to be able to lift a 4WD if I ever get another. Anyone know what height roughly a 4WD wagon would be to the top of its roof with a 6' person standing underneath?
