The Swiss Architecture Yearbook (SAY), published biannually, is an inspiring and informative source for a wide audience interested in architecture. It reflects the country's remarkably diverse architectural production and discusses current trends and challenges in design and construction. Moreover, it provides international visibility for the outstanding quality of Swiss architecture and building culture. SAY's second edition of 2025/26 is again more than merely a selection of the best: it examines topics that concern many people in a time of construction boom and amid the increasingly felt effects of climate change. More than 30 featured projects were selected by an independent international jury from a list of some 160 nominees from all parts of the country. They are supplemented by topical essays asking what the most pressing questions in Swiss architecture discourse are, what defines architecture in Switzerland, and how a sustainable contribution to the quality of life in all parts of the country can be made. Text in English, French, German and Italian.
