An important step up: The first new level is ready
650 tons of steel had to be hoisted onto the bunker roof by cranes in recent months, and around 1,400 cubic meters of concrete were pumped up to a height of 52 meters for the first of a total of five new floors. One of Germany’s largest concrete pumps was used for this construction phase.
The concreting of Level 1 is an important step forward on the way to the publicly accessible “green bunker” high above St. Pauli. After all, the new floor is virtually the foundation of the further increase in height, on which around 180 people have been working since last summer and which will be completed in 2021.
The plants for the new recreation area – around 4,800 trees, woody plants, shrubs, hedges, climbing plants and ground cover – are already growing in the traditional Hamburg nursery Lorenz von Ehren. The predominantly evergreen plants are native to northern Europe – and are thus adapted to more extreme weather conditions, such as those that can prevail at heights of more than 50 meters.
The privately financed project also includes, among other things, a memorial to the victims of the Nazi regime, art and cultural spaces for district initiatives, an event and sports hall, and the “nhow” design and lifestyle hotel. All currently valid leases of the cultural and creative industry companies located in the bunker will remain in place after the increase.
