The function of a storage shed is to keep the outdoor tools you need accessible. This problem is easily solved by a few organizing techniques to keep all your items in reach. By taking the time to create systems and properly store your objects, you can spend more time working on the task at hand.
If you want to go a step further and separate your tools, you'll need to get a bit more creative. One way is to utilize PVC pipe to make containers for your tools by attaching to two pieces of wood and hanging that from the wall. Another solution is to utilize a pegboard for your larger items as well, as they can hang from hooks similarly to smaller items.
