The classical double layer space truss is revisited by replacing diagonals with curved thin-walled polyhedral modules. The expected improvements are both technological and mechanical. The complex 8-branch nodes are broken down into a connection of two overlapping continuous members and a line connection between bars and the polyhedron edges. Curvature in the faces and edges of the modules introduces shape resistance whilst stabilizing the members against buckling. The global optimization of the structure is performed by a form-finding process based on the individual parametrization of the modules. Finally, an experimental validation is carried out by fabricating and testing a full-scale prototype (approximately 6 x 6 m).
