I really like the shed plans. Can probably build this in my backyard, yet, no money for timber yet. Does one happen to know anything about building apprentice I beam saw horses. They can hold a lot of weight. And can be modified to have a tool tray in the bottom. Just an idea. Thats all.
thanks
for the plans i will be able to construct this with all the layout plans and materials
Thanks! How can I build same 12×12 shed? Thank you for your help 🙂
Thanks for the great plan. I modified it to suit my requirements. I added height to the walls so that the back wall was 8 feet high inside. I opted for a single wide door centered in the front and a vent window above the door. I also used 16′ center stud and roof joist spacing and ribbed steel roof panels.
