Cham by Kengo Kuma and Associates


The most “normal wood” used in concrete formwork in Bulgaria is cham. We made a plank with this simple wood, by opening a hole, and weaving it using hemp rope with students of The University of Architecture, Civil Engineering and Geodesy.

By taking advantage of the tension of the hemp rope, an unexpectedly light and soft pavilion was created. By searching for new geometry in parametric design, we were able to recreate the simplicity of Bulgarian private houses and the transparency of Japanese lattice. Source by Kengo Kuma and Associates.
