Diy sheds are cheaper to build than pre-made sheds, and because you are building them yourself from scratch, you can be sure of the quality. this is a key point, because with a pre-made or flat-pack shed, you can never be sure that the lumber being used is of good quality, or even if it came from sustainable sources (if that’s important to you)..
