within the economic development zone of jinhua, china, the ‘cube tube’ office and restaurant building by beijing and tokyo-based practice SAKO architects creates a landmark for the area. contrasting the style of the existing context, a fenestration pattern of varied squares surfaces the main cubic volume and adjacent linear block, generating their respective names, ‘cube’ and ‘tube’.

the nine storey’s of the square structure are intersected with a vertical succession of criss-crossed corridors which terminate as open-air terraces overlooking the landscape. the terminating ends of the pathways feature diversely sized and proportioned rectangles to additional variation. the X-shaped configuration introduces light and breezes into the internal core while allowing a divided working interior space with an airy atmosphere.

as visitors enter the main lobby, they are welcomed with a continuation of the external appearance, as the motif has influenced and been applied to the ceilings, columns, walls and floor tiles. the exterior’s stainless steel curtain wall has been processed with a grinder for its matte reflection. a grid with hundreds of trees surround the site.
