We are mountain people and therefore not necessarily the most outgoing.
However, once we have built relationships, we do not forget them easily.

Architecture Exhibition at Haus Balma

During the spring semester of 2026, the ZHAW Master’s Studio Urban Project, led by Thomas Hildebrand and Mirjam Niemeyer, explored the potential of Valser Quartzite for future construction. Together with Pia and Pius Truffer and the team at Truffer AG, the students explored the quarry and production facilities. The result is five designs that combine traditional applications of Valser Quartzite with contemporary construction methods.
On display are plans, visualisations and models of the projects.

Opening hours
From October 26th 2026, Monday–Friday,
10 am–12 pm and 2–5 pm

Admission
CHF 15.– | Children up to 10 years free
