I have a design. But I want a second opinion. I want to make the shed 10 ft. wide an 12 ft. deep. But I am going to make the side walls 8 foot tall an make it with a peaked roof like a house instead. This being for the ease of the angle cuts. I was going to use a 4 foot rise for the hight of the peak. So the top of the shed will stand a mighty 12 feet. I was wondering if this is overkill.. I plan on putting a loft in it for extra storage.
