You'll find the answer in this article but first let's circle the issue a bit to get a proper perspective. When planning your budget, be sure to consider the various meanings of the word cost. The initial cost is relative to many factors. When thinking of the cost of the barn, consider immediate, short term, long term, maintenance, and associated costs as well as potential savings in each of these categories.
Immediate costs are the initial costs of materials and labor to construct the barn.
So, before you start trying to cut building costs, re-examine the reasons you are building a barn. Whether you are building a Budget Inn or the Equine Ritz Carlton, the building should be safe, healthy, convenient, efficient, and legal. The structure must be strong and well-designed to prevent injuries. It should provide a horse-friendly environment with proper drainage, ventilation, sanitary flooring, protection from the elements, and be comfortable. It should be designed for convenience in performing the daily tasks of feeding and watering and stall cleaning.
