Stairway to h(e)aven

connecting people

Whoever experienced it never could forget it – the 1976 storm flood. The Elbe River rose to 6.45?m above sea level. Five decades later: melting polar ice caps, rising sea levels, ever stronger storms – and Hamburg is still an open gate to the world. Flood protection saves human lives. The quality of life must not be affected by the protective structures, particularly along the Hanseatic city’s most important promenade. A curved stairway creates a new connection to the pulsing heart, linking the river to the city. Elegant, timeless, effective.

paving the way

The complex geometry of the miles-long structure was executed under difficult conditions (high water levels, inner-city location, small area for construction). The existing river walls, which were either integrated in the new structures or demolished, now serve multiple purposes: as promenade, recreation area, event and commercial space, parking facility and – last but definitely not least – as flood protection.

creating construction culture

The new flood protection structure has become a popular attraction. The now wider areas providing access to the water allow a better distribution of the many tourists to various terraces. Large events such as the Hafengeburtstag festival are now easier to hold. The structure, which has been designed to allow for future extension, is not just a visual highlight due to its inviting geometry but also an example of sustainable construction. It will serve its purpose for many years to come without requiring any modifications. GRASSL found extraordinary solutions to realise the exceptional architectural vision of British–Iraqi architect Zaha Hadid.
