Switzerland offers various modular wooden residential construction systems. Specifically, emergency tiny houses, envisioned by firms like Huber and Uffer and funded through crowdfunding verein-ukraine-hilfe, are currently being built in Ukraine, with more than 80 units already completed across the country. The cluster is engaged in a comprehensive exploration of how modular wooden construction can be refined to create affordable housing suitable for urban contexts, serving both as emergency shelters and permanent accommodation. This ambitious endeavor unites the aforementioned firms, collaborating with architects and urban designers from KCAP, along with researchers from the Digital Fabrication at D-ARCH of ETH Zurich. The overarching goal is to pioneer the construction of rapid, sustainable, innovative, and enduring housing ensembles in Ukrainian cities undergoing reconstruction and growth.
