We have been dealing with this construction task for more than 15 years. Our high-rise building in the James residential development was the first residential high-rise in Zurich since the non-profit high-rise buildings Herdern (1976-1979) and Lochergut (1963-1966). The 80 metre high Hard Turm Park tower helped us to further deepen our experience. The construction task holds a huge design potential. In addition, the economic requirements must be combined with the potential for this type of building. What is the added value? What does it mean to live in a high-rise? The following buildings and designs testify to our constant research!

Designing and building a high-rise is one of the most demanding and challenging architectural tasks. In Switzerland, strict conditions apply in terms of urban planning and architecture – because of the height and appearance. The costs are higher than for standard buildings – due to the increased requirements for materials, fire prevention, earthquake protection and wind resistance. Of course, this type of building must also satisfy a holistic approach to sustainability. These complex requirements demand careful planning and open communication with all parties involved.
