My research focuses on the Voidscape, an essential but often overlooked layer of the urbanscape. In Berlin, voids have evolved from post-war ruins and Cold War divisions to sites of memory, experimentation and reinvention. They remain paradoxical: seen by some as spatial resources, by others as missed opportunities for densification. The core question is: How should voids be utilized to meet today’s urban challenges?

This proposal views voids as “space reservoirs”, that can host temporary activation, ecological preservation, or adaptive permanence. By transforming two remnant plots in Berlin-Mitte into an evolving hybrid of architecture and vegetation, the design reframes voids not as gaps to be filled, but as active, long-term contributors to a sustainable and adaptable city. A traditional Berlin perimeter block is reinterpreted to integrate tree-based structures that mature over decades, using species such as Carpinus betulus. These living elements combine with a lightweight steel framework, allowing branches to inosculate, producing a built-botanical system that is structural, ecological, and alive.
