located near the omiya station in saitama, the ‘S-house’ by japanese practice yuusuke karasawa architects represents the simultaneous diversity and order that is ever present in our cyber lives. a central datum of vertical circulation splits opposing 50 m2 platforms that intertwine in the center. what seems like a simple stacking of planes reveals itself to be a rather complex network of diagonal surfaces terminating into one another resulting in an intricate path of circulation from the basement level to the rooftop deck. offset voids in the floor plates bring yet another layer of complexity to the home allowing access to additional functions.

each floor above ground is clad in glass panes to strengthen the structural concept of the home and allows for plenty of natural light and views. private functions are thus located below grade in fully enclosed volumes that serve as the ground-level floor at the entrance.

  • Yes, I would take it from this particular setting and it does bring back memories of ‘Labyrinth’ movie … so how do I get to the kitchen from the 2nd half floor – jump through the gap in the wall. However on a recent visit to Japan I am all inspired by the use of small spaces and what’s actually required for living. Its interesting.

  • DR–Very well said indeed. While reading the article and perusing the photos I was imagining how and where some of my things would fit: books, movies, art. I found plenty of space. I am pretty much ready to move in when my 20 foot container gets to Japan!

  • I saw photos of this house after they had moved in some of the things needed to actually live in it, and the structure looked very different, not so nice. I also dislike the fact that the house has nothing to do with energy efficiency, something that I believe all buildings should be concerned with today.
