Roots Hamburg - Timber hybrid high-rise

Roots in Hamburg's Hafencity is currently the largest timber high-rise in Germany. The 72 metre high tower in hybrid construction comprises 20 usable floors (16 of which are timber construction), which house exhibition rooms, administration and the offices of the German Wildlife Foundation as well as private flats. The lower building, with a total of seven storeys (six of which are timber construction), also houses flats.

The construction method is as follows: Timber construction with a reinforced concrete staircase core on a shared multi-storey reinforced concrete base.

A special feature of the timber construction by Rubner is that:
Factory-prefabricated wall elements in timber frame construction cover an area of 16,200 m². Rubner processed a total of more than 5,500 m³ of softwood in the project, including 4,430 m³ of cross-laminated timber and 820 m³ of special timber.

The large-format exterior wall elements with integrated loggias are particularly impressive in this project. The load-bearing façade elements, which can be up to 14 metres long, were fully prefabricated. This was achieved through the technical integration of Revit and Bocad data. The illustration shows an exploded drawing created in Revit using the Bocad design data.
