Fast fashion is notorious for its high carbon emissions, stemming from various stages like fiber production, clothing manufacturing, and notably, post-use disposal. Our initiative delves into addressing the significant environmental impact of fast fashion waste, particularly its aftermath. Instead of relegating fabric waste to landfills, we propose repurposing it as a permanent building material capable of sequestering carbon. Our approach involves utilizing fabric as a permanent mold for mycelium structures, departing from the conventional plastic molds. By integrating timber structural ribs woven with fabrics and mycelium, we aim to craft robust yet lightweight structures. This endeavor represents a pioneering step toward sustainable architecture, offering a pathway to mitigate carbon emissions and foster eco-friendly building practices. The FIT building, currently limited to conventional classrooms, will be renovated to reflect a commitment to sustainability. This renovation will provide students with new spaces that embrace interdisciplinary courses and activities supporting the exploration of biogenic materials. FIT will become a main hub for the exchange of ideas between the fashion, environmental, and architectural industries, ushering in a new era of fashion and architecture, transcending conventional boundaries and encouraging interdisciplinary collaboration.
