I need plans for a 10 x 12 shed with a shed style roof, I would like a set of free plans if possible , and I would like downloadable plans. By shed style roof , I mean that it is ecentally a flat roof that is raised on one end via a pony wall or a solid wall that is higher in the back and lower in the front , more specificcally a 12 foot wall on the rear, with the rear wall being the 12 foot length side the front wall being a 12 ft length side and the side walls being 10 foot in length. wall heights would be standard 8 foot on the front 12 foot on rear and 8 foot on the sides with a triangular pony wall added to meet the roof. If any one could cad these out with 16 centers that would be a purchase plans set that would be ok too. I would need a scale referance on the set as well. Thanks
