Although the traditional English style of cottage is most typical in America, cottages can be built in a variety of styles depending upon location and the builder's tastes, ranging from Spanish house floor plan designs of the Southwest, which typically have single stories, stucco exteriors, and tile roofs; to Cape Cod cottages which are usually box-like, timber-framed structures two-stories high, with steep roofs to shed rain and snow.
Ranch style architecture originated in the United States in the 1920's, and it became very popular after World War II as cities expanded into suburbs and inexpensive tract homes were needed by a growing populace. Ranch style houses are most popular where land is inexpensive and the weather is mild, since these homes particularly lend themselves to outdoor living. The low, earth hugging look with clean, modern lines of the ranch style is derived from Frank Lloyd Wright's prairie style architecture.
