You will find that the shed blueprints are mostly just that. These are not step-by-step instructional material like you might think. Instead, they are merely design drawings. They include a variety of views, (plan, elevation, perspective), and a description. Sometimes you’ll get a materials list. And while there are admittedly a few that give full instructions, most of them are just shed designs and plans. But because they’re from different sources, some of them are the wrong way round.
Build the framework for all four walls. To account for the fact that the front and back walls are different from each other (due to the doorframe in the front) and the side walls must both be sloped (to prevent rain from collecting on the roof), each of these will have to be tackled somewhat differently. It’s easiest to construct the back first, the front second, and the two sides last, as shown in the numbered image below. See How to Frame a Wall for more information before you read the instructions below.[5]
