In 2020, we launched 24 handmade materials across three different categories: Core Line, Acoustic Line, and Stone Line. While they were grouped based on their surface touch, usage areas, and technical performance, each material in a line has its unique mechanical and visual properties based on its main ingredients.

​

These materials are hand-made or semi hand-made, making them suitable for small to mid-scale productions. As we began to scale production, we positioned them as boutique, high-quality, project-based products and named them Ottan Atelier Materials.

​

Using their core formulas, these materials can be transformed into large-scale factory productions, similar to a continuous factory line. More details about these materials can be found under the "Professional Materials" heading.
