Architecture, Building and Structure Design Poly Chief Palace Sales Center by HYP-ARCH DESIGN Poly Chief Palace is a sales center in the Tiexi District of Shenyang. The facade uses a three-part composition that combines Chinese architectural details with industrial details drawn from the surrounding old industrial base. Pipelines, metal frames and valve assemblies are reinterpreted as building components. In the spatial structure, the Four Treasures of the Study are expressed in architectural language: the wall as paper, a moon-like sculpture as the inkstone, an infinity pool as ink, and trees as the brush.
