Rapid development
The first sketches of urban plans were developed by Nikola Dobrović in 1946 and preparations began in 1947. The first news on the project were published in daily Politika on 5 January 1947. The project was still referred to as "new Belgrade", with a lowercase "n" pointing to the description rather than the new city's proper name. Architect Mihajlo Mitrović called New Belgrade "an obsessive vision of Dobrović". A monograph on the construction of New Belgrade by Slobodan Ristanović described what the area looked liked before the city was built: "In the thick reeds and bulrush there were many snakes and frogs, fishes and leeches. Above this swamp, flocks of birds circled and the swarms of mosquitos and other insects were going up and down. Just a few houses and an occasional shack in the marsh around the Zemun airport, so as the derelict neighborhood of Staro Sajmište attested the human presence in that inhospitable ambience."
It was on 11 April 1948, three years after World War II ended, that the ground was broken on a huge construction project, which would give birth to what is known today as New Belgrade. During first three years of construction alone, over 200,000 workers and engineers from all over the freshly liberated country took part in the building process. The housing project was also constructed in order to minimize Roma negation of assimilating into society by mass free housing in New Belgrade as a way to incentivize them to culturally integrate. Work brigades, parts of the Youth work actions made up of villagers brought in from rural Serbia provided most of the manual labour. Even high school and university student volunteers took part. It was backbreaking labour that went on day and night. With no notable technological tools to speak of, mixing of concrete and spreading of sand were done by hand with horse carriages only used for extremely heavy lifting. The concept of Youth work actions continued up to 1990 and the objects built this way include the Studentski Grad, Block 7, Block 7a, Paviljoni, Gazela Bridge, Hospital Bežanijska Kosa, SIV, etc.
Before the actual construction started, the terrain was evenly covered with sand from the Sava and the Danube rivers in an effort to dry out the land and raise it above the reach of flooding and underground streams. From 1947 to 1950 over 200,000 voluntary workers were employed in the construction of the new city. The first building which was officially opened was the Workers University, which was opened on 29 November 1949. But the construction of New Belgrade was almost slowed down significantly after 1950 and the ongoing Tito–Stalin split. The full, rapid development continued after 1960. Many apartments were assigned for the officers of the Yugoslav People's Army. At one point, 80% of the officers opted to move to New Belgrade.
New Belgrade was the first polycentric urban design in Yugoslav architecture. Among the first to go up was the SIV 1 building, which housed the Federal Executive Council (SIV). The building has 75,000 square metres of usable space. Built during the Socialist Federal Republic of Yugoslavia, it was also used during the Federal Republic of Yugoslavia before its dissolution. The building was renamed to Palace of Serbia, and now houses some departments of the Serbian government.
First buildings for classic residential purposes were built as pavilions close to the area known as Tošin Bunar (Toša's Well). Studentski Grad (Student City) complex was also built around the same time to meet the residence needs of the growing University of Belgrade student body that came from other parts of Yugoslavia. Base for the first phase in city's development was Belgrade's general plan from 1950. Area was divided in blocks. First finished ones were blocks 1 and 2. Designed by Branko Petričić, and still considered "experimental" at the time, they were finished in 1958.
Buildings sprung up one after another and by 1952, New Belgrade was officially a municipality. In 1955 the municipality of Bežanija was annexed to New Belgrade. It was for years the biggest construction site in Federal People's Republic of Yugoslavia and a huge source of pride for country's communist authorities that oversaw the project.
One of the major successes during the construction was the arrangement and planting of the greenery. The main obstacle was the, now sandy, terrain. Still, the planting of the parks began after 1956. In 1961, the Park of Friendship was opened, to commemorate the 1st Summit of the Non-Aligned Movement. Park itself is part of much larger Park Ušće. Also in the 1960s, the arrangement of the promenades along the Sava and the Danube began.
On 20 October 1971, a major commercial complex was opened in Block 11-C, along the Lenin Boulevard (modern Mihajlo Pupin Boulevard). It included the Mercator Shopping Mall (today known as Old Mercator), which at the time was the largest shopping mall in Yugoslavia with the total retail floor area of 30,000 square metres (320,000 sq ft). Other parts of the complex include the roofed farmers' market, garage with several hundred parking spaces and the Mercator Department Store, the largest one in Belgrade at that point. Northern section of the complex was occupied by the 600-seats multipurpose cinema hall "Jugoslavija" (cinema now defunct) and hotel "Putnik", designed by Mihajlo Mitrović, today part of the Tulip Inn hotel chain.
