With its compelling and meticulously realized concept, the newly-opened ALEJA shopping center in the Slovenian capital of Ljubljana, which was designed by ATP architects engineers (Innsbruck), offers the perfect platform for international and local labels in around 80 shops with a total of 32,000 m2 of lettable space. With its rooftop leisure, sport, and relaxation areas and its stylish food court, the technically and architecturally innovative building responds to the competition from online retailers while also giving space back to the surrounding urban district.
