Czechoslavakian architect Josef Kříž built, together with his colleague Adolf Benš (1895-1982), one of the great modern office buildings in Praha in the interwar period, the administrative building of the Electricity Company of Prague. At the proposal of the Directorate Electric Utilities in 1926 both young avant-garde architects won the challenging competition, with the construction taking place from 1930-35. In addition, they planned additional office and industrial buildings, but they also designed a theater. Nothing more is known about Kříž’s life.
