The Washi paper pavilion is an architectural installation by YET Architecture, featured at the Architectural festival Vives in Montpellier, France 2023. Paper as major material is not used so frequently in architecture and therefore the project is a result of a material study around the use of this material. The skin of the pavilion is manually crafted from recycled paper. The whole installation is a mix between digital fabrication and craftsmanship. The general form, paper modules form and their connection were digitally designed to stack together and be in a shape which cannot be repeated using regular sheets of paper. Unlike the papier mache technique, the Washi paper is resulting in a very thin and translucent material without any binder like glue, so it's a completely environmentally friendly material and approach. The mould for the Washi paper module and custom joints were 3d printed and after the mould was used to craft the washi paper pieces. Two hours per day were spent for one piece and it took 24 hours to dry. Therefore its a new way of mixing the digital and physical world, computation and craftsmanship.
Sacredness
The festival revolves around the theme of "sacred," and our installation is designed to elicit a particular emotional response from individuals as they enter the pavilion. The pavilion itself is raised above the ground and suspended from the facades, allowing visitors to appreciate the gentle shapes and translucent patterns created by the paper. By looking upwards towards the sky, one can experience a unique atmosphere characterized by a feeling of lightness and softness. It's as if they are transported to a serene realm, surrounded by the gentle embrace of fluffy clouds, creating an ambience that evokes a sense of tranquillity and serenity. The interaction between people is evolving to a new level, engaging them to become actors or performers for people from outside and vice versa.
Materiality
We examined the wood at various points in its lifetime in order to achieve this objective. Production of paper, a disposable product, is the last stage in wood processing. In order to move beyond this point we want to employ the usage or re-usage of recycled paper. Paper is an ordinary disposable commodity which is commonly not used as a sacred or spatial material for the construction of public spaces, especially recycled ones. However, we look at this as an opportunity to create a temporary structure that will use recycled material to celebrate the last stage of the wood lifecycle. The paper brings a number of advantages. Utilising recycled paper has become possible because of the use of historic Washi paper processes. Structures frequently leave behind a considerable amount of construction waste once they are demolished, with little chance for reuse or to be recycled. Once disassembled, a paper pavilion may be recycled, extending its lifespan while having no environmental impact.
Structurally the pavilion consists of a plywood frame and a net of wooden dowels. The skin of the pavilion is generated from 50 concave custom-fabricated concave paper modules 120cm in length. The form of a module is predesigned and 3d printed in advance and used as a mould for the paper to repeat. Wooden dowels are connected with each other and with paper modules with custom-designed and 3D-printed joints to keep the shape of paper and add stiffness to the installation.
