The horizontal expanse of Emonika City Center will be marked by two elegant vertical elements. The Office Tower at the south of the site with a total height of 100m will be the tallest tower in Ljubljana and the country. As such it should become a memorable and iconic figure symbolizing the importance of Ljubljana and Slovenia. The emonika office tower on the south and residential tower on north define entries to Emonika City Center which bridges the dividing barrier of the railroad tracks, reinforcing and connecting the divided parts of the city. The two Towers as more than skyline statements; they should be part of the urban fabric, which will be created by PCL. Our intention is to treat the two Towers with a contrasting duality by a design, which is based on the regular activity of the Office Tower and the irregular individuality of a Residential Tower. The regular repetition of screening elements of the Office Tower contrasts against the irregular rhythmic, combination of loggias and screens in the Apartment Tower. Together they are stronger than as individual parts and create a formal and material dialogue with one another.
