One solution is to screw a standing pallet into the wall of your shed. Now, you've created vertical storage to easily keep items off the ground.
Buying an outdoor storage building with a loft greatly increases storage capability, allowing you to store rarely used supplies overhead.For the exterior, build your own lean-to and attach it to the outdoor storage building to form a sheltered area for firewood. Outdoor benches are sometimes made to be dual-purpose, offering a compartment to store tools and a cozy spot for taking breathers while mowing the lawn. Potting sheds and small greenhouses are a boon to the true landscaping enthusiast. Some outdoor storage buildings come with large skylights and virtually function as greenhouses in their own right.
