The article discusses the activities of the Institute for the Construction of Cities and its president Vladimír Zákrejs (1880–1948). It explains the origins of the urbanism movement and its connection with the republican empiricism of the era. It provides examples of Zákrejs’s activities in Czech towns and reconstructs the arguments of his inedited manuscript „The Czechoslovak Repulic as an urban building site“. It proves that Zákrejs left the Institute already in 1927 and continued in his activities as an independent urban planner until 1933. His comprehensive approach was replaced by a technocratic tendency, which put emphasis on transport, and a left- -leaning tendency, which focused on housing.
