12x12 Lean to Garden Shed Overview

Are you looking for a medium-size facility that can safely hold your garden supplies year-round? This 12×12 lean-to garden shed is incredibly versatile for storing your garden tools and supplies. 

Providing up to 144 square feet of floor space, the shed is enough for organizing your riding lawn mowers, ATVs, wheelbarrows, rototillers, bags of fertilizers, pesticides, and more. Add drawers, hooks, shelves, and pegboards to make the unit fit your needs.

Besides, you can use the shed as a home office, workshop, firewood shade, kids’ playroom, pet grooming parlor, art studio, tech design studio, recording studio, or any other creative application imaginable. Just furnish and finish it to suit your intended use. 

The shed’s design includes a double-wide, 64-inch wide, 6-feet tall door that offers easy access while giving you an easy time getting things in and out. A sturdy 5′ – 5 1/2″ ramp has been installed at the entrance, allowing you to push wheeled machines and equipment into place quickly. 

There are also two windows with 40-inch sides to keep the inside illuminated for easy retrieval of items. The overall design gives the shed a great appearance, plus you can finish it to match your house and other outbuildings.
