Trlllple Building Site 4

The net structure is symmetrical and regular. Each bar and each node are therefore generally identical. Furthermore, the bars have now been arranged tangentially rather than radially in plan. This leads to greater visibility of the timber structure and, above all, to better utilization of space. The vertical loads of the floor beams are simply transferred to a plug-in system via contact pressure. In the area of the taper of the vase, the deflection forces occurring there are transferred via threaded rods and glued-in pipe connectors.

The interface to the city is developed on the ground floor zone as an urban, paved square. Several insular green areas in the ductus of the circle articulate the space and are planted with trees, they function as a shaded entrance area with seating elements. In analogy to the neighboring high-rise projects, this main access is additionally made visible by a change of sidewalk set off from the surrounding sidewalk. The design principle is inverted for the building greening at the base and on the roof. Here, circles define common areas and are framed by lush intensive greenery.

Following a comprehensive evaluation, we remained with our decision to propose a double layer facade. The external skin provides protection against the weather, the internal layer protects against heat. The low thermal conductivity of wood allows this material to be ideally positioned between the two planes in a space-saving way. In addition, the only penetrations are at certain points of the beams. Thanks to the compact form but also due to the double facade heat losses can be kept to an absolute minimum: at the same time there are large areas of glazing that provide light for the compact floorplans in an ideal way.
