Teixit, meaning “woven” in Catalan, is a 100 m² 3D-printed prototype located in the Collserola Natural Park in Barcelona. Developed by the Institute for Advanced Architecture of Catalonia (IAAC) with 3DWasp Crane technology, it combines 3D-printed earth walls with a prefabricated timber roof. The structure includes a bedroom pavilion, kitchen, and living room. Integrated cavities, reinforced with PVC tubes, allow post-tensioned cables to stabilize the roof with loads of up to 500 kg per cable. Using local soil and natural materials, Teixit demonstrates a low-carbon, km0 approach to sustainable and affordable housing.
