Farmhouse is a general term for the main house of a farm. It is a type of building or house which serves a residential purpose in a rural or agricultural setting. Most often, the surrounding environment will be a farm. Many farm houses are shaped like a T. The perpendicular section is referred to as the ell.

These several buildings tend to be more pragmatic than aesthetic, but often well-stocked or well-furnished in terms of food, insulation or in other aspects dealing with daily necessities. The supply of agricultural products from its environment tends to be a factor for this, as well as stressing the need for productivity and pragmatism in the survival of the farm. The farmhouse allows the farmers, workers and often their families to reside in proximity to their workplace—namely the farm in question. This allows the farmers and workers to arrive at the workplace earlier, increasing the productivity of the farm.
