12x20 Storage Shed Overview

Are you looking for a long-term oversized storage solution to declutter your garage? If yes, this 12×20 storage shed might be ideal for you. 

Offering up to 240 square feet of storage space, this gable shed is perfect for organizing all your backyard elements, including lawn care equipment, garden tools, outdoor furniture, general appliances, and even extra household items. Even better, you can customize the interior with shelves, drawers, pegboards, and workbenches to fit your storage needs and keep your tools of trade neatly organized. The 7′ – 10 3/4″ walls also provide plenty of vertical storage space, where you can add hooks to hang rakes, garden hoes, shovels, and other long-handled items. 

For performance and easy access, the shed comes with a 64-inch double-wide door that allows you to quickly bring all items in and out of place. A sturdy ramp is also included to allow you to push mowers, wheelbarrows, and other things with ease. 

Whatever you want to keep in this shed, it is built using robust lumber and on a reinforced concrete foundation, so it is structurally sound to hold even bulky items. 

You can also use this shed as a workshop, art studio, pub, home office, hobby space, or home business. It is designed to be truly versatile. 

For those keen on aesthetics, the shed is majorly wooden, and you can finish it to your liking. Its gable roof also adds to its classic looks while providing additional space to create overhead loft storage.
