Some of the first houses built in the United States were Cape Cods. The original colonial Cape Cod homes were shingle-sided, one-story cottages with no dormers.
During the mid-20th century, the small, uncomplicated Cape Cod shape became popular in suburban developments.
A 20th-century Cape Cod is square or rectangular with one or one-and-a-half stories and steeply pitched, gabled roofs. It may have dormers and shutters. The siding is usually clapboard or brick.
