Founded in 1989 by four partners and now directed by Kjetil Trædal Thorsen and Craig Dykers, Snøhetta is a Norwegian practice that employs almost 140 people in its two offices, in Oslo and New York. Efficient and poetic at the same time, the architecture of Snøhetta addresses the demands of the market with precision, but never wavering in its commitment to embody the principles of the very best of Nordic tradition, including respect for the landscapes and materials of each context and a deep civic spirit. Such fruitful but difficult devotion to professionalism, poetics, and sustainability all at once – thanks to which the practice has garnered an unquestionable degree of international success – is manifested in the four works featured in the following pages: the subaquatic restaurant ‘Under’, located on the coast of Lindesnes (Norway), the Central Library of Calgary (Canada), the Lascaux IV Caves Museum in Montignac (France), and finally the Grand Opera House of Shanghai (China).
