The „Upcycling Shell“ project is an exploration of sustainable architecture through reuse of mass-produced materials. Building on the concept of digital material that can be reconfigured and reused multiple times. this project explores how discarded everyday objects, especially wire coat hangers, can be transformed into universal building blocks for architectural construction. The main goal is to extend the life cycle of waste materials by transforming them into structurally sound and aesthetically unique forms, thereby reducing ecological footprint of the construction industry.

In a detailed case study conducted at the Frankfurt University of Applied Sciences, a team of students designed and build a 6 x 6 m igloo-like structure from approximately 10,000 recycled wire coat hangers. Dubbed the „Summer Igloo“, this structure server as a proof of concept for how mass produced waste can be used as valuable resource for construction. The design process involved advanced computational methods, including parametric modelling and structural simulation, to optimize the geometry and ensure the stability of the final assembly. The result is a seamless juxtaposition of tetrahedron and octahedron units that demonstrates the potential of digital materials to create complex and resilient structures.

The project not only demonstrates that the use of industrial waste in construction is possible, but also stimulates a wider discussion about the future of sustainable building practices. By using materials that would otherwise down-cycling streams, the Upcycling Shell illustrates a practical approach to circular design, where materials are reused in ever new configurations. This method holds promise for reducing the energy and resource requirements of the construction industry.

This project was initiated by a very dedicated group of students during their 5th semester in a design studio at Frankfurt University of Applied Sciences in 2021. Their dedication and creativity were instrumental in realizing the ambitious goals of the Upcycling Shell and transforming theoretical concepts into a tangible and impactful architectural prototype. Trough their hard work, this project stand as a testament to the potential of collaborative, educational design efforts to address pressing environmental issues in innovative ways.
