12' x 20' Lean-to Shed.

This 12’x20′ modern lean-to shed delivers spacious storage and workspace, perfect for gardening gear, tools, or even a home workshop. We’ve built it with durable LP® SmartSide® siding for long-lasting protection against the elements. Inside, a radiant-barrier lining helps keep temperatures down and your belongings safe. The lean-to design mounts easily against an existing wall, maximizing yard space without sacrificing style or function.
