This project experiments with a new design method through the sequential transformation of four materials: foam, silicone, wax, and concrete. By taking advantage of each material’s specific qualities, the process begins with foam as a soft and carvable medium, used to shape the interior space intended for occupation. Silicone is then applied to cast the negative of this foam-formed space, creating a flexible mold. Melted wax is poured into the silicone mold to produce a duplicate of the original foam form. Finally, the wax is used as a casting medium for concrete, allowing the spatial qualities first carved in foam to be translated into a permanent architectural structure.

Through this craft-based process, the project preserves the traces of hand-making and material transformation. The resulting space carries a highly organic form, shaped not by conventional construction logic but by the physical behavior and expressive potential of the materials themselves. The interior becomes introverted, enclosed, and immersive, offering residents a living experience that feels both protective and deeply intimate. The project proposes architecture as a process of casting memory, where the original carved void is gradually transformed into inhabitable concrete space.
