This is a sale center of Vanke high-end residential building project - Hills, Dalian. The architects chose LOPO terracotta wall tile as the external wall material. Tiles in three shades including brown, light brownish gray, dark brownish gray were blended randomly to create a facade with color gradation. To balance the relatively dark colors of this small building, the designers select small-sized solid wall panels (192 mm wide × 600mm long) instead of conventional-sized terracotta tiles in large format to make the entire building become exquisite.
