For the Summer Festival at Tempelhof Airport on September 1, the young people of the Fliegerwerkstatt are building 12 exhibition pavilions. The materials used come rom the emergency shelter for refugees of the Berlin City Mission in Mertensstraße in Berlin Spandau. At times 1000 refugees were accommodated in 370 cabins. After the closure of the accommodation, the Fliegerwerkstatt saved 24 cabins from disposal and used them to build exhibition pavilions for the Open Day in Tempelhof.
