A consortium (Space&Matter with Metabolic's sustainability plan) transformed the toxic soil using phytoremediation and populated the site with ~17 refurbished houseboats serving as offices for creative and social enterprises, plus a café-restaurant and event spaces. It operates as a 'living lab' for cleantech systems: solar panels, helophyte filters for wastewater, an aquaponics greenhouse, struvite reactors to recover nutrients and the Jouliette token for peer-to-peer energy exchange.● Active· scale local
