Hamburg's response to the Elbtower crisis: What actions is the city taking?
Hamburg's Elbtower Project Stalled Amidst Structural Concerns and Political Challenges
The construction of Hamburg's planned architectural landmark, the Elbtower, has come to a halt since October 2023 due to the insolvency of the developer, Signa[1]. Initially slated to reach 245 meters, making it the third tallest building in Germany, only about 100 meters of the shell frame has been built[1].
The key issue is the settlement of nearby railway infrastructure, particularly affecting the S-/U-Bahn Elbbrücken and Ladestraße railway bridge areas. Alarm values for deformations were exceeded in early 2024, with twisting 1.1‰ and tilting 1.5‰, well beyond the permissible values of 0.7‰ each[1]. These structural concerns prompted interventions such as bridge bearing adjustments in 2022 and 2024 to stabilize the situation. However, even after these adjustments, the values reached the alarm level again in December 2024[1].
The Elbtower's construction is conditional on Deutsche Bahn's approval after settlement issues are resolved[1]. A "crisis team" including experts and a monitoring regime between the railway company and the project owner has been established to manage the situation[1].
Politically, the project faces challenges due to these technical difficulties and the insolvency of the developer. The combination of structural risks, increased costs for remediation, and stakeholder disagreements have significantly jeopardized the originally envisioned timeline and completion.
The city of Hamburg is considering buying or renting space in the lower three floors of the Elbtower for the Natural History Museum of the Leibniz Association[1]. However, the purchase of the space would cost at least 200 million euros, and the rental offer is around 32 €/m2 cold over 20 years[1]. An alternative location for the museum on the DESY site in Bahrenfeld is considered a more realistic option.
Dieter Becken is currently negotiating with the insolvency administrator about a takeover of the Elbtower project[1]. Klaus-Michael Kuhne, a potential investor, remains skeptical about the project's feasibility[1].
The Elbtower, designed by Christoph Felger of David Chipperfield's office, was planned to have 64 floors, with mainly offices, a Nobu Hotel, retail areas, a gym, a spa, an observation platform, wine and gourmet shops, galleries, and cafes[1].
The opposition warns that municipal rental contracts would ultimately burden the taxpayer. Meanwhile, Deutsche Bahn had lodged an objection to the building permit and had secured a contractual agreement that the owner would cover any damages as early as 2021[1].
In conclusion, the Elbtower construction is stalled amid serious foundation and settlement concerns impacting adjacent train infrastructure, with partial remediation efforts underway. Its completion depends on resolving these issues and gaining regulatory and railway company approval, while financial and political opposition remains significant[1][2].
