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.
