‘prefabrication via growth through a closed loop production of biomaterials, fed through a system of organic waste creating a continuous

This project envisions a metabolic co-living habitat in Barcelona’s Poblenou @22 district, addressing the city’s densification and the untapped potential of organic waste recycling. The facility transforms organic waste into sustainable building materials, including biochar produced via pyrolysis, nutrient-rich soil through composting, and bioplastics. Bamboo, chosen for its rapid growth, is cultivated on-site and plays a dual role: initially serving as a structural material for constructing living spaces (domes) and later being repurposed into biochar at the end of its lifecycle.
