City Center one spans two levels connected by elevators and escalators, completely accessible to persons with disabilities and children. The mall is integrated into the urban matrix, placed octagonally in relation to the streets. What makes it different from other malls is its façade with large signs and special lighting, resulting in a play of colours which brings the building to life both during the day and by night. Another special detail that makes the building easily recognizable is the large glass roof which provides daylight during the day, making shopping a more pleasant experience. Wide hallways, bright areas of the mall and transparent glass surfaces make the interior of the mall clear and easy to get around, and pleasant to stay at. The innovative architectural solution was devised by architect Otto Barić, designer was Igor Dombi, while the head contractor was the company Stipić Grupa.
