Some common and popular designs for single-story houses throughout the United States include bungalow and ranch styles. Other types of single-story homes are favored in certain regions of the country, including the shotgun home in the Southwest and the Cape Cod home in the Northeast.
The bungalow has historically been the most popular style of single-story home, according to Quicken Loans. The term refers to any smaller single-floor house that uses space efficiently. Most bungalows have a peaked roof and are square or rectangular in shape. The houses usually have one large main room in the interior center and a series of smaller rooms connected by hallways branching off from the main room.
