Share your wish list and our staff can discuss additional options to your plans, such as electrical or water, manure handling, ventilation, and floor covering. You may choose to have a large run-in or overhang area that provides sun and weather protection for your new barn. After speaking with us, your knowledge of horse barn building will take off like you’re taking flight at Perl Acres Airport. The actual size of a small horse barn depends on the number of horses you have and how you want to care for them. Stepping up your pace with horse barn building is better than a walk at Prospertown Lake Wildlife Management Area.
