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.
Particle board and plywood are composed of pieces of wood products that have been pressed and glued together. Although they are popular siding materials for storage units, they are not most people's first choice in regions where it rains a lot. For if water does work its way into these products (a possibility enhanced by their composite nature), then you're lost.
