If the clutter on your property says one unit isn't enough, but your wallet disagrees, supplement your main unit with one of the less expensive, smaller models. There are three main types of such units, all of which go by descriptive names. $Corner sheds$ are made to fit precisely into a corner and run about 3 feet tall by 3 feet wide by 2 feet deep. Meanwhile, either a $vertical shed$ (5 x 3 x 4) or a $horizontal shed$ (3 x 5 x 4) may be just the handy outdoor storage building to fill your need for additional space.
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.
