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. Architectural styles vary, but very often they are of Cape Cod design. In general styles vary from region to region, but more often the style is simplistic so to serve the needs (and the budget) of the owners.
