Planting start at the bunker St. Pauli

Planting of the gray colossus will begin next week with the first trees. “The start of planting is a great milestone for all of us on the way to the green bunker,” says Henning Lübbe, project manager of the developer Matzen Immobilien KG.

2000m cubic meters of planting substrate are needed

Step by step, the five new floors will then be further landscaped in the coming months. Landscape gardeners and landscape architects are working flat out to complete a large part of the planting by early 2023. The exact date will depend crucially on the weather in the coming winter months.

Since September, the substrate is distributed on the levels

The substrate has already been blown onto the designated bunker areas at a height of more than 50 meters since September. A total of around 2,000 cubic meters of the nutrient-rich special mixture, which was specially prepared for the green bunker, will be needed for the 4,700 plants that will turn the St. Pauli bunker into a spectacular natural oasis.

In times of climate change, the planting of the Bunker St. Pauli has a model function for projects of a similar kind all over the world. After all, heat waves, droughts, heavy rainfall and air pollution also affect international metropolises in particular. The interest in practical experience is immense. To provide scientific evidence of the effects of greening, sensors have been installed throughout the bunker to record data such as evaporative cooling and thermal insulation for five years. Climate experts from the TU Berlin are evaluating the data to precisely record the climatic effects on the building and the microclimate in the neighborhood and make them available to future international projects.
