The paper unfolds a work of Synergetic Landscapes unit of Master of Architectural Design at the Welsh School of Architecture. This collaborative design unit focuses on generating potentials for coperforming landscape of human and non-human, living and non-living, natural and artificial participants of Grangetown community, Cardiff, Wales, UK. The term community in this project is extended from what used to be understood in anthropocentric culture. In 21st century, i.e. rivers (such as Whanganui River) and others are reclaiming their legal personhood. This work aims to integrate variety of living and non-living agents within the community in codesigning flourishing environment with and for All. It aims for transition towards the era of Post-Anthropocene where living and non-living beings and systems coexist together in synergy. The methodology of Systems Oriented Design and full-scale prototyping has been implemented into a real life codesign laboratory that is performing in real life and real time.
