price out tuff sheds, good value.
otherwise 5 4x4 posts down each 20ft side, 40ft of 4x8, about 10 sheets of 1/2" plywood to cover the roof, 400sqft of shingles, about 22-25 2x6x20's for roof trusses. then all the a$$ociated connectors and any siding you want will add to the need for studs as well.
you are looking at 2000-2500 in materials to do it right.
