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.
Design of Outdoor Storage Sheds and House Design - Remember that these structures are not merely for storing things away. In addition to their usefulness, the appearance of outdoor storage sheds affects the overall appearance of the property on which they are installed. As such, the unit you choose should be of a design that complements your home. Select one with a rustic design (for instance, board and batten) for a country-style house. If your house's style is more formal, select an outdoor storage shed with formal features to match (for instance, if your house has an arched window, carry the theme over to your outbuilding).
