At 215 meters, the Zalmhaven project in Rotterdam is the tallest prefabricated building in the world. Using a crane, one floor (250 m²) was added to the building each week. This was only the fourth time in the world that a structure had been built in this way, and it once again required a new form of prefabricated construction, for which Senta developed a custom-made anchoring system. This anchoring system is similar to the one used for Galaxy Tower.
