text: 21st century In 2010, the first international architectural design competition in almost 30 years was organized for one of the future symbols of Belgrade in Block 39. It was the project of the Center for Promotion of Science. Out of 232 submissions, the work of Wolfgang Tschapeller was selected. The design of an elevated, ethereal building, which was to appear from distance as hovering, was supported by the architects, but not much by the public. Main problem was the price. Initially estimated to cost €10 million and to be finished by 2014, the projected price skyrocketed to €65 million and the construction never began. Local architects now called the project a colossal waste of money and in 2015 government scrapped the project all together. In July 2020 it was announced that the massive new police building will be built on the location, which remained undeveloped.
  Since the 2000s, and especially in the 2010s, the rapid development resumed in the southwest half of the municipality, bounded by the streets Tošin Bunar, Vojvođanska, Milutina Milankovića and Sava's left bank. Prior to this. one of the central streets in the neighborhood, Omladinskih Brigada, was urbanized "here and there", with buildings humble in both architectural merits or functionality and this section of New Belgrade was considered to be neglected in terms or architecture and urbanism. In one decade, new boulevards were constructed (Heroes of Košare Boulevard), while numerous large buildings and objects sprawled along the boulevards, including some entire neighborhoods and residential or business blocks: Airport City Belgrade, Delta City, West 65 (will be  tall), Savada, A Block, Novi Minel, Roda shopping mall, Ekstra shopping mall, hotels, gas stations, many business highrise, etc.
