I.R.A. / international royal architecture: ISM house

‘ISM house’ by I.R.A., chiba, japan all images courtesy of I.R.A.




japanese firm international royal architecture, or I.R.A., has completed ‘ISM house’ in isumi, chiba, japan. the area developed on a large scale as a resort property near the sea, while most of other sites remain untouched since the owner of land can not determine the site boundary or road location. intended for a client who likes fishing, this cottage stands amongst a vast field of weeds without the ability to see the ocean, mountains or beautiful greenery.


taking the sectional shape of the white arrow, the structure was built without an important context. the form which is not recklessly opened to its large site, but is opened inside to interior rooms. an inner and deep terrace under the eaves which penetrate the center of a building. the roof is constituted by the stress skin panel structure which consists of assorted wood. the attic space is floating, with gentle connections to the framing while it reflects the indirect light from behind the eaves and fills each divided room with light. the whole building is wrapped with FRP waterproofing which is easy to maintain and has anti-rust properties. the performance of the home resists strong damage from salt water in the air.

  • Would make a nice house in rural Panama, CR, etc.. ..with solar panels, LEDs.. Nice.

    Jim C says:
  • Правильно! а зачем людям окна?

    Putik says:
  • So tired of psudo spaces. This looks like an industrial tool shed/gas station in the works. No truly livable interior space, no privacy. Windowless, bunker exterior. It appears cheaply foreboding in the context of it’s surrounds. Does Japan have a process whereby the community weighs in on new buildings, or must they simply endure
    whatever is dropped in their back and front yards?
