Comparison of Siding Materials for Storage Units - Natural wood is considered by many the most attractive siding for storage units. But wood exposed over time to water usually rots. Some woods, however, contain natural resins that make them relatively rot-resistant. Cedar is such a wood and very popular as a siding choice for storage units. But even cedar siding is not maintenance-free. Coat cedar with a UV-inhibiting sealer/preservative every other year to protect it from ultraviolet solar radiation. Apply a clear stain, as well, to help preserve its natural beauty.
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).
