House (Latin domus; German Haus) is one of the 12 sections of a natal chart, each corresponding to a specific sphere of life.

Houses as "where", signs as "what". The house system superimposes a terrestrial frame on the celestial map: if the zodiac signs are "what" (energy), then the houses are "where" (the sphere of life).
