kazuyo sejima: shibaura house office building, tokyo

japanese architect kazuyo sejima has completed ‘shibaura house‘, a multistorey building containing flexible workshop spaces located in shibaura tokyo, japan. this bustling new center positioned within the business district and a short walking distance from main transportation lines provides diverse areas within the various levels. capable of supporting a wide range of functions and activities, individuals or groups may hold meetings, conferences, events, lectures and exhibitions within unique interior and terraced plan arrangements.

the tensioned steel structure supports a glass curtain wall penetrated with intermittent setbacks containing open air terraces on the front and back elevations. upon entering the premises, visitors find the ground floor lounge is open to the public, furnished with chairs and tables for universal usage. upper study levels are connected to the primary focal patio with a curving staircase integrating an outdoor experience into regularly traveled circulation paths. the ‘bird room’ is perched at the highest story providing a versatile space for dance classes and communal gathering filled with ample daylight.

  • This drawing is very beautifull. thank you for making us still believe in simplicity.

    IDon LAB says:
  • Nice use of natural light!

    Dario says:
  • terrible mesh – cuting cost?

    labo says:
  • the drawing is nice.
    but with so much transparency, and generally lack of operable windows, it feels rather hot at the height of summer, doesn’t it?

    dh says:
  • Luxury of space

    Fernando says:
  • playful layout, almost like a doll house (with all the pros and cons), i imagine the elevator is housed within that central core? the stairs seem a bit tight for a space used by so many people.

    dennis says:
  • The drawing looks far better than the actual building.

    Jiji says:
  • did really great job. her works is so unique, different from any japanese architects. the spaces are truly distinguished.

    zuhdi says:
  • Wow, I wonder how rich the owner is. The house is comparable size as the 50+ unit condo next to it!
