Plastic Storage Sheds For the Yard or Garden
Choosing a Plastic Storage Unit from Suncast, Rubbermaid or Lifetime Sheds 
If you thought wood or metal sheds were your only choice, think again. Another option for your garden storage is to buy a plastic shed. Modern plastics, especially resin or vinyl, can provide a long lasting alternative to wood and metal sheds. They are also easy to maintain and keep clean, as well as being comparatively easy to assemble.
Some of the most popular plastic sheds come from Lifetime and Suncast, with their maintenance free storage units. Lifetime Sheds are generally between $1000 and $2000, with a good range of sizes such as 8 x 5, 8 x 7.5, 10 x 8, 8 x 10, 15 x 8 and 8 x 12.5. Suncast plastic storage units include the 7.5 x 10, 10 x 12.5 and 10 x 10.
Your stock of garden tools, machinery and other outdoor items you may wish to store, will dictate your shed size. If you only have a few tools, and no machinery or patio furniture that needs storing, then a simple vertical plastic storage shed may be ideal and economic. There is a good variety available in stores and online, so you should find something suitable for storing garden tools and other small items
The vertical style of storage unit suits small yards in particular, or a tiny garden. On the other hand, if your existing shed is in good condition, but overflowing, then an additional vertical plastic shed could provide you with a solution. These locker style sheds are very handy, and are great for garden tools. Depending on what you need to store, you may prefer a horizontal storage shed. Think carefully before deciding which gives you best access to your tools.
Plastic storage sheds need not be just the small vertical type, though, as larger sheds are available too. For example, a robust 7' x 7' shed with wide doors could store that new garden tractor/mower which you had your eye on last summer. Resin sheds are available from Rubbermaid and other well known manufacturers of outdoor storage sheds. There are so many other sizes available, as mentioned above from Lifetime and Suncast.
The important thing is not to rush your decision in choosing a new shed, whether made from plastic, metal or traditional wood. Companies like Arrow, Suncast, Lifetime and Rubbermaid produce a lot of modern sheds, but there are also many other manufacturers who make wooden sheds in traditional styles but with modern appeal.
A final thought if you only need to store a small number of items. You can always find some extra space in dual purpose storage seats or deck boxes. That could solve your problem and save you cash at the same time.
