Homes have evolved over the years and the major trends have been the result of builders wanting better more efficient homes for their clients. After World War I and II the world was introduced to new materials and construction methods, the International and Usonian Styles were the result. Usonian has a unique history associated with Frank Lloyd Wright but it can represent a more natural approach used to improve the home environment and many features are similar to the International Style. Green homes are the present day future in home building. The U.S. Green Building Council’s Leadership in Energy and Environmental Design guidelines can help any homeowner understand how to improve his home and enjoy living there while saving money.
