Terrain vague

21st century cities face many challenges. Overpopulation, pollution, suburbanization, rising land prices, gentrification. And yet never in the history of mankind has such a percentage of the world's population lived in cities, and this trend will increase. One of the keys to such cities are large deserted areas in the urban organism. These seemingly dull spaces wedged into the urban structure offer unprecedented potential for renewal. The potential of the return to the city and the transformation of its image into the form in which we want to live. The last unoccupied spaces where urbanism can be revived.
