Proof of Concept is a dynamic exhibition platform exploring the intricate and captivating processes behind design. Showcasing work from a collective of multidisciplinary studios, it highlights self–initiated projects, products that never reached the market, and designs already in circulation. By shedding light on the extensive development process, the exhibition offers a rare glimpse into the evolution of a product—revealing the ideas, challenges, and creativity that shape its journey.

Proof of Concept — Connect is an exhibition that explores how materials, processes, construction and craftsmanship shape our relationship with everyday objects. Designers are invited to consider the role of tactile experiences, traditional techniques, and innovation in forging deeper connections between makers, users, and the spaces we inhabit. Through this exploration, the exhibition celebrates the tangible bonds that bring design to life.
