Before deciding to have a barn built, you have to first determine what you need in a barn. This will help your barn construction contractor choose which designs to suggest. Here is a brief look at the most common types of barns available.
A common size for a horse barn is 36x48. This size allows for 12x12 horse stalls to be placed among the structural support poles, on each side of the barn. Most horse barns have a front and back entrance in the center, making it essentially a drive-thru barn. It is easier for a vehicle and horse trailer to enter the barn, load and unload the animals, and then drive right out rather than having to struggle with backing up a trailer. Depending on how many horse stalls are needed, unused stalls are typically used as a tack room for storage of saddles and other related items. Feed and hay may also be stored in one of the stall sections.
Common agricultural barn sizes are 30x50 or 40x60. Housing livestock depends on which animals will be housed there. The barn has to meet both the needs of the farmer as well as the animals. Beef cattle need to spend the majority of their time outdoors to avoid the spread of disease and parasites. Beef cattle basically only need a wind break barn, basically an open manger they can gather in in inclement weather. On the other hand, dairy cows, which aren't as hearty as beef cattle, aren't suited to living outdoors. When they are done grazing in the pasture each day, they need to be milked and then allowed to retire to their stanchions or rest area. Dairy barns frequently have an attached milk house as well.
A pole barn uses poles as the support structure for the outer walls and roof. The poles are typically made of wood, although they made be made of steel. The outside shell of the barn is generally metal siding. Occasionally, a concrete foundation is laid, but more often than not, the pole barn simply has a dirt floor. They are available in several standard sizes. They may be used to house livestock, storing feed and hay, as a workshop where equipment is repaired or manufactured, or as a machine shed for tractors and other farming equipment. Pole barns can be quickly and inexpensively constructed, but they can also be susceptible to high winds and are best built in areas where sustained strong winds and tornadoes aren't likely.
