This study provides an overview of ongoing research on cross-laminated timber (CLT) panels bent with the lattice hinge method: a system that has been explored by ArtBuild and Ney & Partners WOW for two temporary structures. First, the parameters that define the lattice hinge cutting process are described and exposed at the scale of CLT panels. Second, the results of a series of experimental tests will be investigated to define the structural behaviour and properties of slotted CLT panels. Finally, the two projects that were built will be presented in terms of architecture and structural details. The first one is a pavilion built for the Libramont Fair in 2019, and the second one, is an ephemeral auditorium that has been set up in the ephemeral Grand Palais in Paris for the International Wooden Construction Forum (Forum Bois Construction) in 2021.
