We went crazy at this point and purchased a load of 2x3's and a few 2x4's to frame out the walls. 2x3's are plenty structurally sound for building shed walls in our climate and they offer the bonus of giving a few more inches of space on an interior and are usually cheaper than 2x4's. Since our shed is shorter than the standard 8' boards we used the extra pieces cut at 45 degrees to reinforce the corners. Normally this wouldn't be structurally necessary as the exterior plywood gives lateral stability. But since we were using very random sized recycled plywood I thought this would help add stability.



We found a door at a recycling center and framed that in at this time since door openings are often tricky to work with and made a slight tilt to our roof for shedding water. Our climate is mild and snow is rare so you would probably want more of a tilt in other climates. We also tilted ours to the south since we would later be adding a solar setup.

Sheds are rarely very tall, our framing is 7 feet at the highest point. This will help keep your design more accessibly sized AND keep down any excessive use of materials. There are many great instructables that can help you through basic framing, I liked the framing section in How to build a garage from the ground up by jmengel if you need to learn basic framing design.



I actually framed this out by myself but this is one of those jobs that would be a lot easier with a friend to help hold things. You should be regularly measuring between corners to make sure everything is square and this is also much easier with two people.

Remember to keep your design MODERN with basic shapes and lack of adornment. This will not only give you good clean lines but keep your project simple and easy to work with. The battle cry of modernism is "Form follows function" which was originally expressed by Frank Lloyd Wright's early mentor Louis Sullivan, meaning that the result of design should derive directly from its purpose.
