takeshi hosaka architects: roomroom

kanagawa-based practice takeshi hosaka architects has shared with us images of ‘roomroom’, a two storey dwelling for a deaf couple and their children in the itabashi ward of tokyo, japan. conceived as an annex to their main house which sits adjacent to the project, the design considers the clients’ communication needs by perforating the walls, roof, and floor with a number of 200 mm squares to facilitate a way to visually tie the inhabitants together throughout the residence.

situated on a corner of a dense block, the house reads as a small rectangular volume with a series of small square-shaped windows marking its facades. the random arrangement of the apertures creates a visually distinct identity for the structure while maximizing privacy for the living space within and maintaining natural light intake. circumscribed with a high railing, a roof top terrace can be clearly observed from the street level.

organized as two small rooms on the ground floor and a large open space on the second level, the language of the exterior is continued to the interior through a collection of internal windows on the layout. the children sometimes call their parents’ attention by dropping a small toy through the openings and use sign language to communicate between storeys. some of the apertures allow plants to grow through the floor from the lower level, further establishing a sense of connection throughout the design. the windows can be seen as an interpretation of a common atrium – enabling light, sound, and wind to travel freely between two elevations – which provide a practical solution specific to the needs of the clients.

  • claustrofobic!

    veru says:
  • so many windows and no view

    Rok says:
  • Isn’t this a bit dangerous?.. There’s a child crawling round a floor dotted with holes.

    Kuba says:
  • It’s quite brilliant. Look at the details. But I guess this family has no needs related to eating or eliminating, as there is no kitchen or bathroom. And whats with the drinking fountain on the first floor? There is a mysterious institutional feel to this place…kinda scary.

    MkC says:
  • Oh, foolish me. This space is attached to the main house, where the daily domestic activities take place.

    MkC says:
  • Es el claro ejemplo de lo que pasa cuando se busca la originalidad y el esnobismo por encima de todo. encuentro a esta casa totalmente invivible, la profusion de ventanas genera privacidad, ventilacion y nivel de luz totalmente incontrolables. La terraza es espantosa, no se puede ni caminar con tantas ventanas y obstaculos. Parece mentira que con el problema de falta de espacio que existe en japon se desaprovechen tantos metros cuadrados. No quisiera tener que cuidar a ese niño dentro de la casa y menos en la terraza. En resumen me parece un hermoso objeto de exposicion, pero solo eso un ejercicio de espacios y formas

    Arch Antonio Vaggione says:
  • Kind of magic.

    Matthias says:
  • An amazing piece of architecture. Well planned out and executed.

    phil says:
  • I wouldn’t like to be the widow cleaner!
    Looks quite fun, perhaps they are still saving up for some proper furniture so the poor little boy can sit down!
    All done for the magazines and Architects ego , I fear.

  • I think with myself…what is a Church? Is nothing more than a symbolic demonstration of power.
    It’s funny when these kind of house is posted here, there’s a lot people commenting with fear or angry when an Architect do a piece of Icon for ordinary people.
    There’s a lot of things that came from Churchs, and I think that there’s a lot of things that we can think and could come from these houses.

    baiacu says:
  • Be still, my heart.
    This is absolutely beautiful.

    jess lynn says:
  • ok, honey, i am off to work… star closing the windows… (after 15 min.)… cmon honey, there is still 37 to go…
