Text description provided by the architects. Located at the edge of Place d'Youville, in the heart of Québec City's cultural district, Le Diamant transforms the former YMCA, a Second Empire building constructed in 1879, into a multidisciplinary centre for theatrical creation and performance. Developed for Ex Machina, the project combines the preservation of the historic building with the insertion of a 625-seat multifunctional theatre, a creation studio and new public spaces.
