The concept is a "Serene Marble Passage." The corridor uses cream-grey marble walls with natural patterns, paired with a polished stone floor that reflects light, making the space feel wide and calm. Hidden LED strips run along the curved wall edges, guiding the eye and creating a soft, warm glow without harsh light. Dark brown wood trim adds a refined five-star hotel touch. Connecting areas have large potted trees in natural stone planters, mixing luxury with a relaxed, green feeling — making it feel more like walking through a luxury seaside spa than a normal hallway.
