Slit House



  This house is made "only" by the slits. There is no window. 
  A　wall 105m in length with 60 slits surrounds the site and realizes the architectural space in this   
  narrow and long site. No other architecture has ever been realized by such a method.


  This conceptual sculpturing by the slits is poles apart from glass-heavy contemporary  
  architecture. This method with the slits is our challenge to "window". 
  This challenge is an experiment to innovate a design method of architecture. 
  The concept to compose the architecture just by the slits directly figures this architecture. 
  This simple method distinguishes the outline of the entire figure and abstracts the stance of the 
  architecture.







  The site is located in an old city in Japan, where many private houses stand in a row. 
  The site size is 50m deep and 7.5m wide. One of two narrow frontages faces a street and the 
  other faces a river. We designed a long wall that encloses this narrow and long site. 
  The slits open this enclosure. The 140mm wide slits screen inner privacy from outside views. 
  But the slits bring 60 lights into the house. This proposes one method to live in a dense residential 
  area in Japan where houses stand side by side.

  An 80 year-old woman lives in this house. 
  The house presents her both a life space with a soft light and an interesting experience of scale 
  unlikely in a house.




  The slits make us more sensitive to light. The interior space is light beyond our expectations. 
  Light through the slits varies its appearance momentarily according to weather, season and time.   
  The slits remind us our old experience in memory with poetic scenery. 
  It looks like a stream of light through Fusuma or Shoji in Japanese traditional architecture or a 
  stream of light from a skylight of ancient stone architecture.





  This architecture has a silent ambiance just as in the midst of a solitary jar and a poetic clearness 
  as in an endless spatiality. 
  The slits hold the promise of an innovative design method of architecture.








The Slit House has its own special time.

  At dawn, watery light comes into the house through the slits, and makes the entire room faintly  
  bright.
  
  At 9:30AM,sequence of the feeble light that reflects to header of slits appears. 
  
  At 10:30AM, the sunlight pierces through angled slits first.

  At 11:00AM,the sunlight pierces through all the slits. 

  The sunlight through the slit and the reflected light on the header of the slit project the stripe of 
  V type through the long corridor. 
  If you saw the repetition of this edgy light, you might feel as if time of 11:00AM has stopped. 
  In as little as ten minutes, the reflected light on the header disappears. 
  The shape of the light that the slit makes changes from V type into one stripe.
  The moments that the sun pierces through the angled slits and through the straight slits are 
  different.
  The angled slits get a little earlier.
  The momentary time lag lets us feel a running of the sun and makes us sense the upcoming time of
  the dusk.
  And it shortens little by little. And watery light fills the house again with soft brightness. 
  Then the night comes before long.
