Architectural Patterns
A series of well-developed architectural styles or vocabularies were popular throughout the United States in the 19th and early 20th century. These styles were adapted by local builders through the use of early pattern books and later catalogs of house plans. 
Many early houses were built without the aid of pattern books and are increasingly rare. These styles represent the broader patterns found in the neighborhoods constructed largely before 1940. Each style has become adapted to the local environment and local building traditions.
Five principal architectural styles can be found throughout the United States, which when adapted to local requirements, give neighborhoods unique character. These styles are described in more detail with typical key elements in the following pages.
- Classical and Colonial Revival
- Victorian
- Arts & Crafts
- Mission
