NEW SHED PLANS | A GAMBREL SHED is a beautiful that looks like a red barn. In our effort to get ready for spring we thought that a few larger gambrel shed plans would be great to offer people who want a larger shed with a lot of style. So here they are, the 12×12 and 12×16 gambrel shed plans. They both have a loft area that greatly increases their storage capacity. Check out all the great gambrel shed plans.
