The Kádár cube (Hungarian: Kádár-kocka) is a vernacular style of detached houses which was the prominent style of suburban and rural housing built in Hungary during the so-called Kádár era. Kádár cubes were relatively small single-storey buildings (bungalows) with a generally square floor plan and hip roofs. Their total floor area is generally around 100 m2. A number of Kádár cubes were built according to or based on governmentally developed building plans.
