Marlène Leroux, partner at Atelier Archiplein in Geneva, was invited by Prof. Emmanuel Rey’s studio at the Laboratory of Architecture and Sustainable Technologies (LAST) to talk about her work as an architect through a selection of projects. Entitled " Construction durable ou l'utilité cachée de l’inutile", her talk gave students the opportunity to discover projects that tackled, in particular, the construction and sustainability challenges of using solid stone.
