Marc Leschelier is a French architect based in Paris. He builds architectures without function, entitled pre-architectures, in open spaces, sculpture parks, or any situation exempt from urban regulations. While inventing an architectural genre through the development of alternative constructive systems, Leschelier responds to the sclerosis of the architectural discipline by creating an immediate, naked, speaking architecture. Drawing inspiration from performance art, vernacular architecture and industrial materials, Leschelier weaves together multiple languages in an attempt to break architecture’s process and bring it into sync with the speed of the present.

Marc Leschelier was a fellow at the Villa Medici in 2017–2018 and at Casa Wabi this year. His work has been awarded by Herzog and De Meuron with the redistribution of their prize at the Académie des Beaux-Arts in Paris. He is the guest architect for an 1700 sqm installation in Florence for Pitti Uomo 2026. In March 2025, he opened a solo show in Paris in dialogue with historic pieces by Jean Prouvé on loan from a private collector. He has exhibited his work at Christophe Gaillard Gallery, Mascota, Ketabi Bourdet, and Everyday Gallery. He has participated in international fairs such as Design Miami Paris, Salone del Mobile and Art Brussels. Over the past six years, he has built nine permanent and ephemeral pavilions.
