Map of Clay — Boltshauser Architekten

Winner of the Swiss Art Awards 2025 in the architecture category, Map of Clay is realised this year as part of the exhibition. Over the course of a year, Boltshauser Architekten collected clay samples from across Switzerland, documenting the country’s varied soil types and regions. In the exhibition hall, vibrating sieves animate the different clays, forming a material map on the floor — a catalogue of colours, textures and origins. Map of Clay makes geology tangible and proposes clay as a sustainable, regionally sourced building material.
