As with all complex projects, there are tricks to the trade. The material list and instruction guide is based on building environments on the East Coast. For areas west, where snow loads and wind gusts are stronger, other engineering factors may need to be considered. For this particular project, post holes are approximately 3-feet deep. Areas west of Mississippi may require post hole depths of 5-feet, thus requiring additional concrete mix as well.
Site selection is very important for three-sided buildings.
Obviously, with an open front, you want to shield the horses from the elements, especially those cold arctic winds. Consider the prevailing winds and position the building's opening away from the wind. Whenever possible, utilize existing wind breaks, such as trees and other buildings. Also, consider a site where in the deep of winter you can easily access your building by food or by vehicle. Convenience to water hydrants is a plus.
