Traditional House Plans are some of the most common styles built throughout the United States. These floor plans are designed to accommodate the American way of life. Traditional House Plans are kind of a mix of several other styles, but there are some basics that are usually consistent throughout traditional home plan designs: simple roofline, often hip rather than gable. Brick or stucco exteriors are most common. Traditional style homes are often single level floor plans with steeper roof pitches, though lofts or bonus rooms are quite common. Other popular features of traditional floor plans are covered porches and open foyers.
