hideyuki nakayama architects: Y house

the ‘Y house’ in hiroshima japan is designed by hideyuki nakayama architects and has been introduced by JA+U (Japan Architecture+Urbanism. a white exterior wall curves down the length of this narrow lot, creating a color-coordinated relationship with its neighbor. the 95 square meter dwelling was conceived as both a ‘gray cliff’ and ‘white valley’, using a windowless exposed concrete facade to overlook the bordering empty lot. a roof slopes downwards towards the driveway, introducing daylight reflecting from the adjacent three-storey tall building through skylights. the indirect illumination within the upper level creates an attic-like atmosphere for the bedrooms.

  • Lighting? What is with the terrible fixtures, or lack thereof, in Japanese homes such as these.
    I also wonder why there is this interest in standing out in the neighborhood.
    The society that can be known for its ability to work together and think of the common good gets more western as time goes by.
    I don’t think this residential design would be as appealing, nor as visible, if the entire neighborhood was filled with hundreds and hundreds of bizarre shapes.
    This is a “Look at me” sculpture. Not appealing architecture.

  • @Mark W,

    Yes there are.

  • Like the external line of the design.As for the interior; the ceiling seems very low,as if it was crushing the space.
    We see very little of the interior. Where is the bathroom?
    Love the exterior curved line.The design is interesting,but somewhat small. Maybe a higher structure would have balance it off with the rest of it’s surroundings in which it is sitting.Still the exterior is a nice design.

  • Are there light/ventilation, fire exit, access requirements, electrical/lighting minimums in Japan building codes?
