The four-story office building constructed from timber offers space for around 300 workstations, a cafeteria, and an underground garage. The energy-efficient new building, funded by the state of Rhineland-Palatinate, is modularly designed, making it easy to expand or dismantle. The sustainable building concept, which utilizes natural materials, has been consistently planned and implemented.
The building was designed as a timber skeleton construction. The volume forms an elongated U shape, with a two-story pavilion featuring the main entrance positioned in the center.
Due to interlocking connections in both the load-bearing structure made of glued laminated timber and in the execution of the ceilings made of cross-laminated timber (provided by the construction site), it was largely possible to avoid steel components, which would otherwise have needed to be clad to meet fire protection requirements.
The ventilated facade consists of a timber frame construction made of individual elements with cladding of coated, pre-grayed spruce that ages naturally. Rubner constructed, prefabricated, and assembled approximately 3,840 m² of facade with wall elements, around 566 wood-aluminum windows, and 230 m² of post-and-beam facades for the building envelope in just eight months on-site. By prefabricating the timber components parallel to the solid construction of the underground garage and stairwells, the timber load-bearing structure and the outer facade could be installed immediately after the completion of the shell structure.
Thanks to the façade landscape, the new building presents itself as a new architectural highlight of the Mainz-Bingen district.
