I’ve decided to go with a 8′ x 12′ shed. I think that will make the best use of materials since the metal comes in 3′ sections. I’m going with a single pitch, or shed style roof. I can get 12′ sections and if I over hang them 6″ on the front and about 6-1/2′ on the back. This will give me a covered area behind the shed to park an old ridding mower that I use to pull trailers around my property. I still have to figure out the construction details and buy materials, but I’m sure I’ll be able to figure it as I go.
