Green Vein Station reimagines Sandiaoling as an open, healthy, community hub. Set in a mountain valley, the redesign replaces the current poorly lit, stuffy, crowded layout with simple forms, clear lines, and natural materials. It brings daylight and fresh air back in, improves circulation and the wait-to-travel experience, adds friendly health services, and creates places to meet, rest, and view the landscape. The station becomes a soft, inclusive public building that links transport and daily life—a welcoming gateway for the region.
