The Shed Roof, the classic "Lean-to", is one of our most popular accessories to the basic Gambrel Barn design. It's not only practical but extremely versatile. The plans for the Shed Roof include details for an open post and beam side or front porch, depending on how your barn is situated, as well as details for a completely enclosed, "walled-in" version with doors and windows, so you have a choice! Use the plans to build an open, inviting front entry, a bug-proof screen room or completely enclose it for additional interior square footage.
