Agricultural buildings often have special grading and site preparation requirements and on a much larger scale. All agricultural buildings need a level site and often a concrete foundation.
Pole barns are a popular agricultural building because of the ease of construction and simplicity of the build. Pole barns do not have a fixed foundation but have poles set in concrete along the perimeter of the building.
Properties with slope can be regraded or you can take advantage of the slope to create a multilevel agricultural building. This is often advantageous because the building can have ground access on more than one level. A bank barn can be used to take advantage of a sloping site and allow multi-level access to the barn easily.
Other Equestrian Structures
In combination with a horse barn, you may desire to have an indoor or outdoor equestrian arena. Both cases require a level site preparation and often a storm water management solution.
