future-scape architects: house in musashi koyama

future-scape architects has completed ‘house in musashi koyama’, a single family residence located in tokyo, japan. a ground level garage for the dweller’s vehicles raised the program an additional floor higher than surrounding neighbors. alternating bands of black galvanized steel plate and glass in combination with a stepped building profile minimize the appearance of the structure’s height from the street.


the interior walls and floors are finished with andean rose on the first level, cherry wood on the second level and beech wood veneer on the third, becoming lighter at each successive level. giving a distinctive character to the rooms heightens the inhabitants awareness of their ascent through the structure and a sense of their location. horizontal ribbons of insulating windows introduce natural light to the spaces with walkout terraces formed as the floor plates becomes smaller.

  • Very nice the dark wood used in the first room!

    Dario says:
  • interesting how the wood gets lighter as you move up. One would think that you would use the lighter wood on the ground floor to brighten up the spaces, as it’s harder to get natural light to the bottom.

    nice project, but some shots with furniture and people would be nice – this is architecture that is used by people, not some sterile object.
