The Greek urban design project “e_co_llectiva” by Athanasios Polyzoidis (Architect-Landscape Architect) and Katerina Petsiou (Architect) was awarded with the Salon Grand Prix in the 4th Landscape Architecture Exhibition in Belgrade. In their design, the public space of the streets and the vacant lots in the internal parts of the four building blocks is unified so as to create a single urban garden-park which promotes the concept of collective activity. This intervention is given the title ‘e_co_llectiva’ after ecology (eco), collectivity (collectiva) and new technologies (e). More images and architects’ description after the break.
