The topic of the final thesis is the urban and architectural design of the Retfala South Business Zone, located in the southwest part of the city of Osijek. The urban design determines the position of nine commercial buildings, surrounded by a botanical garden, with an elevated walkway on the first-floor level between them, extending beyond the scope to address the city's infrastructure issues. The architectural design focuses on one of the commercial buildings, defined by the hybrid typology, in the northern area of the site. The architectural concept continues the initial goals of the urban design, emphasizing the individual, human scale, pedestrian movement, and vistas provided by the botanical garden. The urban design principles are connected and complemented by the concept of hybridity. Through the exploration of the hybrid concept in various disciplines and their interconnections, a hybrid building emerges as a combination of a slab and a tower, with fluid floor plans to accommodate the botanical garden and interconnected floors through various means of communication, such as staircases, elevators, a panoramic lift, and a hybrid communication slide. By adding communication elements to the basic structure of the building, it becomes equipped for life, and by incorporating various functions, the hybrid building becomes a living organism 24/7. The building is ready to accommodate planned and unplanned activities, offering a variety of amenities such as exhibition spaces, a marketplace, cafes, a cafeteria, rental office spaces, and more. It is connected to the urban promenade that passes through it, reducing its floor area. The building provides facilities for the community and company employees while also creating spaces for individuals within hybrid rooms designed based on research on the psychological impact of work, emotions, and colors—a sort of sanctuary and escape from reality. The textile membrane on the building facade reduces its vibrancy, while fully embodying the concept of hybridity.
