In August 2017, Stattwerk has disclosed its plans for the building, saying that it will be the first energy-efficient skyscraper with green facades in Serbia with different commercial and tourist facilities. The official bid for the best project of the completely green building (just sun, wind and geothermal energy) was announced in October 2017, and the winning project was picked in December. The new, "green skyscraper", projected by architect Jovan Mitrović, will include the green façades, automated underground garage for 500 cars, photovoltaic panels, organic recycling and garden, greenhouse, etc. No dates on the construction were given. In December 2017, an artistic installation was placed inside the building. Stretching from top to the bottom for 12 floors, it consists of recycled green canvases which form a tree-like structure. Using decorative lights and natural winds, as the building is without windows, it mimics the real, green tree. It is named Biotop.
