Classicism reigned in the mid-19th century as our country settled into independence and moved away from colonial English styles and toward the more romantic, classical styles of ancient Greece. Today’s architectural interpretations may incorporate elements of Classical style, such as pediments, grand entry porches, and elegant columns. Most of all, attention to proper proportion characterizes these timeless house plan designs. In this category you’ll discover a variety of house plan styles, including Greek Revival house plans and Adam Federal style house plans. These formal styles are at home on a large country estate or formal urban lot. But there’s no need to be formal inside; many Classical styles can include modern open concept layouts and relaxed island kitchens. Consider a layout with the master suite on the main floor or an in-law suite downstairs to make it easier to age in place or house an elderly relative later.
