A hall and parlor house, also known as a "saltbox" or "double-cell" house, is a style of housing commonly found in early American architecture. The term "hall and parlor" refers to the layout of the house, where the main entryway leads into a central hallway (the "hall"), with rooms on either side (the "parlor"). Synonyms for this type of house include "double-hung," "double-house," and "side-hall" houses. Other similar house styles include "shotgun" houses, where rooms are arranged in a straight line from front to back, and "dogtrot" houses, where a central hallway separates two living quarters.
