The 4' sidewall "Mini Barn" is a very economical building. It is our lowest profile building. It is also our lowest priced building per square foot. If you don't need overhead storage or a lot of wall space, this may be the building for you. All 4' sidewall "Mini Barns" are available with all of our options. Although, the loft may not be very practical due to the lower overall height of these buildings.
