Over the past three decades, we have conceived a diverse range of visionary studies—both in Switzerland and abroad—that, while not realized, illustrate our enduring commitment to forward-thinking design. Our approaches often integrate **digital fabrication**, **sustainability**, and **human-centered planning**, creating bold concepts that prioritize both functionality and well-being. Many of these studies explore **mixed-use environments**, underscoring the importance of shared spaces and flexible architectures adaptable to future needs. By combining Swiss building expertise with international inspiration—from São Paulo to New York—we have developed proposals that push creative and technological boundaries. Although unbuilt, these designs inform and invigorate our current projects, ensuring that innovation remains central to our practice.
