In 1934 and 1935, the Griprogor Institute, based in Leningrad, created a master plan for the construction of Dushanbe. It was approved on 3 March 1938. The city center during the reconstruction shifted to Red Square and Frunze Park, the location of many workers demonstrations and military parades into the forties. In the later half of the decade, much of the modern infrastructure and utilities for the city were created. In the 1940s, architecture was focused more on decoration and the neoclassical style.
