Interior Space and Exhibition Design Guanlan Yipin Sales Center by Hongfei Yan Guanlan Yipin is a sales center located in Suzhou, China. The design combines an oriental character with a minimalist approach, following the idea of a garden tour that guides visitors through the space. Marble, metal, sandstone and wood set the tone of the interior. Dai Cyan, a traditional Chinese color, appears as marble on a wall six meters wide and ten meters high. Facing the marble wall, eight panels of laminated super-white tempered glass, each 0.8 meters wide and ten meters high, stand beside the landscape stair. Large windows bring natural light and greenery into the interior.
