We were asked to provide a public space for all seasons, including a refrigerated skating rink and a service pavilion, that would not interfere with the mandate of the Partenariat du Quartier des Spectacles to offer a wide variety of activities and experiences in a constant state of flux. It led us to propose a thin linear service building defining the western edge of the esplanade and to extend the skating surface along St-Catherine street while preserving a grassy surface on the northern side for a main mobile stage. Movable planters and furniture occupy the space during summer to keep it alive and vibrant all the time. The service pavilion is an assemblage of wood boxes over a post and beam concrete plinth. The abundant fenestration includes folding glass walls on the ground floor and allows access to heated terraces on the first floor. The project includes a loading dock with two oversize freight elevators to bring urban furniture and scenic equipment of the Quartier des Spectacles down to the large storage space in the basement. The green roof includes an herb and vegetable garden maintained by the operator of the restaurant. Thirty-six geothermal wells located under the rink surface provide energy to cool and heat the building as well as the heat dissipated by the compressors of the refrigeration system which is reused. The integrated design process brought together the multidisciplinary team and the client in a collaborative environment for this $50M project that has been completed in 2022.
