The project reimagines a historic red-brick building in Seoul’s Marronnier Park as a community-oriented creative learning environment centered on making, play, and interaction with nature. Rather than treating the existing structure as a fixed monument, the design introduces a series of lightweight timber and textile insertions that weave through and around the building, creating a gradual transition between the institutional interior and the public landscape of the park. The proposal is guided by the concept of “Woven Transition,” where architecture acts as an intermediary condition rather than a clearly defined boundary. A flexible framework of modular wooden elements, translucent fabrics, and simple joinery systems extends from the historic masonry, softening its rigid character and establishing a network of sheltered outdoor rooms, workshops, and gathering spaces. These additions create a porous edge that encourages movement, curiosity, and informal encounters between children, visitors, and the surrounding community. Inspired by ideas of clean and dirty crafting, the project accommodates both structured learning and spontaneous experimentation. Spaces are organized around making, exploration, and play, allowing activities to spill outdoors and engage directly with the changing environment of the park. Through adaptable construction methods and a tactile material palette, the intervention emphasizes participation, creativity, and collective use, transforming the former institutional building into an open, evolving place of exchange where nature, craft, and everyday life become inseparable.
