Roots Timber High-Rise

Roots in Hamburg’s HafenCity is Germany’s tallest timber high-rise to date and an example of the potential of timber in building construction. The Hamburg-based architectural firm Störmer Murphy and Partners GbR designed the building using solid timber construction: the load-bearing material for the residential floors is timber, whilst individual components such as the stairwells and the building’s plinth are made of concrete. Schöck products used in the interior ensure safe and efficient thermal insulation as well as effective impact sound insulation.

With a gross floor area of 36,200 square metres, Garbe Immobilien-Projekte GmbH has created 181 flats, as well as office space and exhibition areas for the German Wildlife Foundation. Adjacent to the 65-metre-high tower is a seven-storey, L-shaped block.

In the wing building, Schöck Isokorb T S, in a special design, ensures the secure and thermally decoupled connection of the cantilevered reinforced concrete balconies to the solid timber floors made of cross-laminated timber. Thermal bridges between the timber floor and the reinforced concrete balconies were thus prevented through the use of this load-bearing thermal insulation element.

The timber structure of the high-rise tower rests on a sort of reinforced concrete ‘table’ above the second floor. To prevent this from projecting outwards, the overhang was designed as a wraparound balcony. Among other things, Isokorb XT K ensures the energy-efficient and structurally reliable connection of the freely cantilevered reinforced concrete slabs.

Den effektiven Trittschallschutz in den Treppenhäusern der Erschließungskerne sichert Schöck Tronsole: Die Anschlüsse der Fertigteil-Treppenläufe an die Podeste wie auch an die Bodenplatten wurden mit dem Trittschalldämmelement ausgeführt.

Schöck Tronsole ensures effective impact sound insulation in the stairwells of the circulation cores: the connections between the precast stair flights and the landings, as well as to the floor slabs, were constructed using the impact sound insulation element.
