This house located in Nagoya city has three functions: a flower shop, an art gallery and living quarters. Here, these three spaces which are normally separated,break the unseen barriers and integrate with each other. With flowers displayed in the gallery, they become art.


With art in the flower shop, it becomes closer to life. With the living quarters blending with the shop space, the time it takes to arrange flowers becomes richer. With the display space in the art gallery crossing an invisible border line, we even wanted to cross the borders that define ‘home’.


On the north face of the property, an elementary school provides an unchanging environment for the future. This property,which looks out onto the schoolyard, offers an enjoyable view of the trees and flowers that have been planted there.

In an effort to blend the first floor art gallery and flower shop with the walkway leading to the school, we created an open space incorporating the walkway as part of the building’s exterior.


Utilizing the height of the ceilings of the first floor,we have framed the walkway to the schoolyard and procured the views of the cherry blossoms, tender spring leaves, and the autumn foliage. It is almost as though the school yard is an extended part of the flower shop.


The second and third floors have been built to minimize the effects of noise from the walkway by building a spacious opening on only the north side. Soft, natural light allows the owner to enjoy the plants and flowers in the most beautiful way.

By opening the architecture to the surrounding environment, we have created the opportunity to blend the ground to the building, the building to the people, and the people to other people.

    Ugh spiral staircases. You know what they say about spiral staircases… Didn’t take the time to properly solve the floorplan.

    • jocy

      I don’t think so.
      when I saw the spiral staircases,
      the curve in the handrail of a staircase and stairs,
      I feel that it’s funny and contracted

      disagree. the stair is light and delicate and doesn’t take up much space in plan. it’s about efficiency and transparency.

    This one is really enjoyable. I wonder whether the ‘folded’ slab is structurally practical or just for visual purposes. I remember an example of this kind of structure in the book ‘Why Buildings Stand Up’ (or soemthing like that). The way it was presented left you in no doubt about how and why it worked.

  • Brad

    Great section and beautiful stairs, too bad you could never use them in America.

  • brandon pass

    I agree with tripicalismo360. By the looks of the section, it very well could be a ‘folded plate’ assembly. very strong and economical precast components. The section leads me to believe it is just that with a topping slab to level.

    I disagree with INawe about the spiral stairs though. Although I am not always a fan of spiral stairs, I do believe they have their place if properly composed. Are we to believe you think Oscar Niemeyer or Le Corbusier did not properly solve the plan to these masterpieces?

    great work with the origamistyle concrete, would be nice though if the foldings gave space to something in the floorplan (e.g. a real staircase). spiral stairs are not my favourite, but having said that this one is very beautiful! rear elevation a wee bit ordinary and inconsequent – shouldn´t the origami-theme be able to solve all elevations? anyway, it´s beautiful, concrete looks of very high quality and the light on the folded walls and ceiling is impressive!

    @INawe… although spiral stairs may be an after thought in some designs, it doesn’t seem like the case for this one… with trying to incorporate the three components (flower shop, gallery, and living space), the stairs start to become a sculptural living organism within the space. kind of like a breath of fresh air.

    the drawings of the floor plans could be more accurate in detailing, but all in all— this is still a beautiful space. i think the photography captures it quite well.

    omg! the only japanese guy with no digital camera! Priceless, love the photos with dust on them.

    The house is just superb and the stairs beautiful.

  • imagine

    really nice, love it

  • luna

    i do not understand why the ceiling is folded too? for the structure or else?

  • andreas

    it is absolutely brilliant! very talented!

    great job – yet again. i agree that the stairs are gorgeous. the pic 7 (?) is fantastic showing the flowing delicacy that can be achieved. spiral staircases are commonplace in contemporary residential japanese architecture due to the lack of space to do otherwise. its true the buiding codes allow a high ratio of tread to riser than in the usa and australia, but not to the level required for this project i would assume.

    the term “origami” certainly seems aparent in this case. another interesting point is the location of the project, being somewhat isolated on the sidewalk, opposite a high school – you almost expect it to be a newstand or something. strange but true, and the more you know about japanese architecture the more you expect anomolies on every street.

    great job!

    the spiral stair case is nice but what is there to stop anyone from walking right up them and robbing you when your back is turned?

    Hey, thanks for the great post. Honestly, about four months ago I started using the internet and there is so much junk out there. I appreciate that you put excellent content out that is clear and well-written. Good luck and thank you for the great article.
