Traditional homes 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 homes are kind of a mix of several other styles but there are some basics that are usually consistent throughout traditional designs: Simple, often hipped rooflines. Brick or stucco exteriors are most common. Traditional plans are often single level floor plans with steeper roof pitches though lofts or bonus rooms are quite common. Covered porches. Open foyers.
