Woven breathing façade: hygroscopic responsive textile architecture

Project development: United Kingdom

Woven Breathing Façade reimagines architecture as a living, adaptive organism. Conceived as a self-regulating system, it passively responds to heat, humidity, and rainfall by harnessing the hygroscopic properties of wood. Without electricity or mechanical components, its woven elements expand and contract with atmospheric shifts, opening to ventilate, closing to protect, and continually negotiating with the surrounding climate.

Instead of relying on technological complexity or artificial control, the project draws on the intrinsic intelligence of natural materials. Inspired by traditional basket-weaving techniques, the façade transforms wood’s innate hygroscopic capacity into a responsive textile. Each stitch functions as a pore, tightening or loosening with environmental change, creating a living weave that breathes with its context.

Over the course of the biennale, the installation will remain in motion. Subtle shifts in temperature, humidity, and even the presence of visitors will activate the façade, turning it into a slow performance of coexistence with natural forces.

At a time of climate extremes and ecological urgency, Woven Breathing Façade offers an alternative vision for the built environment. Rather than sealed, isolated systems dependent on energy-intensive infrastructures, it imagines buildings as porous membranes—sensitive, adaptive, and alive. This bio-inspired approach proposes a radical shift in how we design and inhabit space: an architecture that does not impose control, but instead listens, senses, and evolves in resonance with the rhythms of its environment.

NOTE OF CONDOLENCE

With deep sorrow, the Brazilian Institute of Architects – São Paulo Department (IABsp) mourns the passing of architect and landscape architect Kongjian Yu, a global leader in ecological urbanism, and the members of his team who accompanied him, tragically killed during the filming of a documentary. The institute is honored to have had him as a participant in the 14th São Paulo International Architecture Biennial, where his transformative vision strengthened the dialogue between global challenges and local realities. IABsp emphasizes that Yu's contribution, which transcends borders, will remain an inspiration for generations and expresses its condolences to China, to the families of all the deceased, to his friends, and to all those impacted by his genius and dedication.
