French Chateau, or Chateauesque, is a style based on the monumental French country homes built in the Loire Valley from the 1400s to 1600s. Typically built in an asymmetrical plan, these homes feature complex rooflines and facades with many recessing and protruding planes. Roofs are steeply pitched and hipped, sometimes with cast-iron crests. Architectural details are elaborate and feature quoins and keystones, as well as other architectural details. Stone, brick, and stucco are common exterior materials.
