Barns have evolved. Much of our rural farmland has been subdivided. Many farms have become smaller, and with these changes, came the need for a new type of small barn commonly called a storage barn. Today, instead of having one large barn that serves many purposes, we may have several smaller buildings which each serve single purposes, like a small barn for animal feed, an equipment shop, and a small run in shed. These storage barns are often portable buildings, and may change locations on the property to meet changing needs.
