Phase 1 involves the construction of the Air Serbia administrative building, consisting of a ground floor, four upper floors and a recessed top floor, with a total gross floor area of 7.985 square metres. Its height mirrors that of the Aviation Museum, located on the plot next to it. The initial phase also includes the development of part of the internal access road linking the complex to Nova 5 Street, which will serve all future phases of the site. In addition, landscaped and green areas will be arranged, along with an open-air parking facility in the north-western section of the plot providing 140 parking spaces, six of which are reserved for persons with disabilities. A new ring road and street is also planned on the other side of the complex.
