SAKO architects: cube tube

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.

  • yo dawg, i heard you like randomly distributed squares..

    te says:
  • window licker – aphex twin…

    diego says:
  • I actually really like it! From the outside it’s a little strange but the interior shots are beautiful! and think about all the light that enters! Very surreal but nice.

    gaia says:
  • re. what gaia says, the inside reminds me of a sculpture that we have at tel aviv university. it is outside in the grass of the grounds, and it is just a metal frame. but when you look through it you see straight through, down the grounds and the street off towards the sea, and it becomes almost like if it is a painting (sometimes moving, if the people and cars are moving!) the pictures in this article of the windows inside reminds me of this!

    sasha says:
  • > if that suppose to be a concept of randomness, it is well predicted
