Colonial Revival was a design movement popular in the United States in the early- and mid-1900s. It drew inspiration from the original American Colonial home. Almost half of all homes built during this period featured this style of architecture and interior decor.
The easiest way to know if a home is an original colonial house or part of the Colonial Revival movement is to look up its construction date. If your home looks colonial but was built anytime in the 1900s, it qualifies as Colonial Revival.
