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 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.
