seele was appointed to implement three challenging packages: the 335sqm roof system, the interior façade to the multipurpose room and 490m of balustrades in bent toughened safety glass. The roof system with its many components enables specific ventilation for the atrium and natural lighting for the interior. The 335sqm roof structure consists of mainly triangular insulating glass units with glass beams and aluminium sections attached with adhesive.
The 180sqm multipurpose room is formed by solid glued laminated timber members and complex trapezoidal panes of glass. The architects specified northern red oak from America for the glulam members, which had to comply with the stipulations of FSC certification. In order to achieve the high production quality required for the glulam members, every single one was designed in 3D and the data sent directly to a five-axis CNC machine for processing. seele’s implementation concept satisfied the high demands regarding the complex details and the stipulations regarding sustainability. It was crucial that the puristic glass look be maintained for the glass balustrades. Each balustrade is supported along the bottom edge of the glass, with horizontal loads being carried by an adhesive joint in structural glazing quality between the stainless steel and glass. The design work was backed up by intensive testing.
