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.
Outdoor Storage Sheds as Part of the Landscape - Integrate your outbuilding into the surrounding landscape. Plants can help outdoor storage sheds blend into a yard, rather than sticking out like sore thumbs. Establish garden beds around your unit and plant them with annuals or perennials. You can also install trellises up against the walls of outdoor storage sheds and adorn the walls with vine plants.
