Vertical sponge city above Hamburg
With its intensively greened roof and façade areas, the extended High Bunker in Hamburg‘s St. Pauli district, which now boasts five floors, is based on the principle of the sponge city.
Drainage ensures greenery
This vertical sponge city was made possible thanks to an innovative drainage concept that utilised ACO products. On the roof terraces and on the façade around the barrier-free entrances, channels ensure effective rainwater absorption. On the approximately 560 metre-long green ‘mountain path’, ACO Self® turf honeycombs promote greening, accessibility and the elimination of paving.
