From time to time flame wars appear on the Polish SSC section in the threads about Łódź concerning whether there should be skyscrapers in Łódź or not
Why not? Because there is still a lot of unoccupied areas in the city center, and there is simply no need to go up when the city has space to spread "horizontally". For example, this exact area which is gonna be the "new city center".
Another obstacle, for the region of the city where the skyscrapers would be most desired, is that you can't go too high over there because it would interrupt the operation of the airport, which is quite close to the city center (and this is one of the advantages of Łódź).
