The topic of the final thesis is the urban and architectural solution for the Retfala - South business zone, which is located in the southwestern part of the city of Osijek, serving as an entrance and exit point to this part of the city. By analyzing the current state of the area, a main green promenade is incorporated into the business complex, surrounded by eight business buildings of various typologies, as well as hotel and market buildings. As part of the architectural solution, one of the business buildings located in the northern part of the area is designed. The building features a hybrid typology consisting of a slab and two smaller towers. The starting point of the concept is based on the building's typology itself. The two towers represent dual but complementary volumetric characteristics. The northern tower and its corresponding half of the slab are envisioned as empty spaces with solid volumes, while the southern tower and the other half of the slab represent solid volumes with perforated empty spaces. The structure of the installation from the main promenade of the urban solution fits into the resulting voids of the building like a network of columns and beams. This installation structure creates a distinct character for the building, which interacts with the solid volume in areas where the two entities meet. The interplay between the solid part of the building and the airy, slender installation structure forms a coherent whole, creating a contrast in the material of the two structures—concrete and steel. The slab volume accommodates public spaces such as exhibition areas and cafes, while the tower volumes house more private sections of the building, including various design departments. The variability of different ambiances stimulates users' desire for further exploration and forming their own impressions of the vistas and the experiences the building has to offer.
