For nearly maintenance-free storage units, vinyl is the preferred siding. Vinyl lacks the visual appeal of wood, but if you own a house with vinyl siding, why not select a storage unit that is also sided with vinyl? However, vinyl will get dirty over time, making it even less attractive. Mold is often the culprit. Take into account the maintenance required to clean the vinyl periodically.
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.
