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.

Eldvarm was founded in 2015 with a simple belief: the objects that live alongside a fire should be as considered as the moments they frame. What began as a focus on fireplace accessories has grown into a wider collection of objects for the home, each one designed to earn its place and last. Louise Varre started the brand from a personal place, shaped by growing up in Scandinavia where fire is part of everyday life. From the beginning, she chose to work with designers who share her commitment to beauty, function and material honesty. Every piece is made in small European workshops, by hand where possible, using natural materials chosen for how they age as much as how they look. In a world busy doing, Eldvarm wants to create moments of being.
