The topic of the final paper is the urban and architecutural solution of the business zone Retfala - south, which is located in the western part of the city of Osijek. The location of business buildings was determined by the urban plan. Also, urban planning defines the position of the stamps of nine office buildings that will be located on one plot, and whose underground garages/floors will be included in their plots. On the ground floor of the building, they have the possibility of connecting to the public promenade on the level of the first floor. The architectural solution deals with the project of one of the office buildings. The concept of the architectural solution continues with the originally set goals of the urban solution. Providing users with various means of using parterre urbanism, walkability, a very clear division of purposes, extending the botanical garden, creating facades with different characters (dichotomy) are just some of the goals. The business zone Retfala - south is located right next to the western entrance to the city of Osijek and Svilajska Street, and these directions represent two important traffic axes when entering the city of Osijek from the western side. The office building that is the subject of the architectural design is located in the southwestern part of the second in line. And as such, it can create a very important facade and the entire scope, so the concept has developed on a dichotomy, that is (0 i 1). The solution of the building rests on the dichotomy of the facade, space, etc. precisely because of the emphasis on the contrast between the road as the entrance to the city and the botanical garden, the concept creates two different facades, one that is fenced off from traffic and the other that opens up according to the values of the urban planning.During the design, attention was also paid to the contents that will be important for the further development of the company. A clear division of purposes in the interior of the building is ensured so that the end user can intuitively use the space.
