Garden Storage Shed Plans DIY Gable Roof Design Backyard Utility House 10' x 20' After following hard to understand drawings from books and the internet I decided to design and build my own sheds. I use the latest building practices and AutoCAD software to design these. This is for a 10' X 20' Gable roof shed. I like the size and design. I altered my own shed from these plans to include a opening on the end so my Grandson and myself could build a row boat in it and get it out when we were done. All plans are designed by Ben Stone. Ben is a retired Engineer in Canada. Ben also drafts these himself using the latest AutoCAD software to ensure accuracy. He studied Engineering back in the early 1980's. After over 30 years in the Construction industry he developed a passion for building cool items around his farm and cabin. These are great DIY projects. With a little skill anybody can Do It Yourself. Ben is always a email away if you have any questions while building one of his projects. He is adding new plans all the time.
