According to the design for the building of the House of National Representation, including the interior design, it was envisaged that sculptures should be the most important decorative  elements, which would be the expression of artistic values and visual manifestation of national, spiritual and political identity. Already in the twenties of the last century, according to the idea of the architect Ilkic, the sculptures should have been placed at both entrances and along the upper edge of the lateral wings of the buildings. With their symbolic character, the sculptures were supposed to refer to the function of the institution and its importance. However, this concept was not implemented, but the decision was made to place the selected cast models, created in the period from 1925 to 1926, in the interior of the building. Nine works have been preserved: Defence and Miner by D. Arambasic, Science by P. Palavicini, Traffic by L. Dolinar, Handicraft by I. Kerdic, Trade by Z. Lukic, Politician by I. Zajec, Gardener by I. Napotnik and the Constructor, probably by D. Hotko. These versatile sculptures reflect the main artistic streams in sculpture of that period a great deal.

Upon the construction of the building, towards the end of the thirties, the sculptures were placed in niches designed for that purpose inside the building and they present more harmonized entirety. In the vestibule, at the very entrance, there are four monumental sculptures in the marble of Prilep, of firm, stable forms and slightly stylized, reduced surfaces, which present the individuals who symbolize the historical development of all three constitutive peoples and the founder of the royal dynasty. Those are Tsar Dusan by D. Filipovic, King Tomislav by V. Radaus, Prince Kocelj by T. Kos and Karadjordje by F. Krsinic. The sculptures in the central hall, according to the planned concept, present the economic activities and are expressed by female figures with attributes pertaining to certain economic branches. The figures Handicraft and Sailing, the works of P. Palavicini and Agriculture and Industry, by F. Gorse are made of marble. The related works are the personifications of Justice and Education, two works by F. Krsinic, made of bronze. The mentioned works were created according to the models that won the first awards at the competition in which almost all known Yugoslav sculptors from that time took part in.

As part of the interior design, the busts of King Aleksandar, Nikola Pasic and Stjepan Radic were ordered from R. Stijovic, T. Rosandic and S. Stojanovic, and then I. Despic made a portrait of the King Petar II in 1937.

During the post-war period, as of 1947, the busts of Josic Broz Tito were created by A. Augustincic and B. Kalin, as well as the busts of the Chairmen of the Federal Parliament Mosa Pijade, Dr. Ivan Ribar, Milentije Popovic, Edvard Kardelj by A. Augustincic, B. Kalin, N. Jankovic and Z. Kalin.

The sculptures in the building of the National Assembly are the works of the most imminent authors from the territory of the former Yugoslavia. With regards to their artistic value, they  are among the highest achievements in Yugoslav sculpture, especially sculpture in the period between the two World Wars. Regarding the designing concept, they make a harmonious and thoughtful entirety which reflects the historical, spiritual and material development of the state.
