Lee Sisan (b. 1995) is a South Korean designer and artist based in Seoul whose practice spans furniture, lighting, sculpture, and spatial design. Originally trained in interior design, he developed a deep appreciation for the natural world while studying in a landscape surrounded by mountains and rivers. Fascinated by the individuality of stone and its resistance to standardization, he explores the dialogue between nature and artificiality, tradition and modernity, translating these tensions into contemporary functional objects.

Working across materials including stone, wood, leather, and metal, Lee embraces experimentation to reveal their inherent character and expressive potential. Through a refined design language rooted in material honesty and craftsmanship, he creates sculptural works that balance purity of form with everyday function. Alongside his independent practice, he co-founded the spatial design studio PRACTICE in 2020, extending his multidisciplinary approach across architecture, interiors, and exhibition design.
