Interior Space and Exhibition Design Beichen Optometric Center by Ke Luo Beichen is an optometric center located in Tianjin, covering 368 square meters over three floors. A spiral staircase links the floors and rises in a transparent, winding form. White guardrails on the second and third floors are shaped to suggest human eyes, highlighting the ophthalmic specialty of the clinic. Arcs, rings and rounded corners are repeated in the ceiling, the back wall, the stairs and the reception desk. Green plants, trees and custom leather sofas soften the space. The design combines medical, commercial and artistic needs in one warm and professional interior.
