The Bangkok Hospital Urology OPD is a 910 sq.m. refurbishment project inspired by the balance between warm hospitality and a cool, relaxing atmosphere. Designed under the concept “Flow with Smooth,” the space introduces ripple-inspired curves, soft blue gradation tones, and fluid architectural elements to create a calming patient experience. Indirect lighting is strategically integrated to visually soften the low ceiling condition and enhance spatial openness. Through seamless forms, subtle transitions, and light-driven design, the project transforms a conventional outpatient department into a smooth, contemporary, and human-centered healthcare environment.
