For Lars Loebner, a green space is not just a green space. „Rainwater from the roofs of surrounding buildings can also seep into a green space or a playground,“ explains the department head at the Berlin Senate Department for Urban Development. To achieve this, of course, the area has to be planned accordingly. Together with his team of around 50 people, Loebner is developing new neighborhoods in the German capital. In the process, he is always thinking about the climate. „After all, we want to build sustainable neighborhoods that our grandchildren’s generation can still live in.“
