**5. Dr Ivan Ribar Settlement and "Smelly Buildings"**

At the initiative of the City of Belgrade in 2010, the realization of the Program for the construction of social and affordable apartments at the location Dr Ivan Ribar in New Belgrade continued. As was the case with other locations planned for this purpose, an architectural-urban competition was announced by the Association of Belgrade Architects for this location in 2011. In total, 53 works were submitted to the competition, and the first prize was awarded to the RAUM architects from Belgrade [63]. According to the jury, RAUM's proposal (see Figure 4) met all the criteria set by the tender conditions, especially in terms of the expected structure, square footage and organization of housing units in the buildings.

Housing units are organized into six identical buildings of two-tract type, considered a rational solution from the aspect of project implementation. By forming two types of inner courtyards, a high quality of housing was achieved in the settlement, namely green areas with rest areas and a modified hilly relief that regulates the views and provides privacy and peace [63]. The free area on the western part of the plot, which is unfavorable for construction, is arranged as a green park area where sports and recreational facilities and sports fields are located.

The project was realized with minor changes (see Figure 5) by the Construction Directorate of Serbia according to the first-prize winning competition solution, and the first apartments were occupied in October 2013. As planned, the apartments in this complex belong to the categories of social and affordable housing but are built so that there is no difference in terms of quality of construction.

The main investor of this project was the Construction Directorate of Serbia (CDS), which was also responsible for the sale of the apartments, as well as for guaranteeing their quality. According to the Law [62], the CDS engaged several domestic construction companies to construct particular buildings within the complex. The engaged companies independently carried out the stages of the process on individual facilities that were the subject of their work, which included the procurement and purchase of construction materials and equipment produced in Serbia (70% of the total amount of construction materials and equipment). The domestic construction company, Koto d.o.o., was engaged and responsible for the building of Buildings 1 and 3, which would later be known as "smelly buildings."
