Double House by Tsuyoshi Kawata


Architect Tsuyoshi Kawata of Japanese studio Tonoma has completed a house in Hyōgo, Japan, that's divided in two by a narrow strip of garden.

Called Double House, the wooden-framed two-storey house is unequally divided.

The roofs of each part are angled, admitting sunlight through the gap between the buildings and into the interior through large windows.

Photographs are by Takumi Ota.

The text below is from Tsuyoshi Kawata:

Double House has been customized by small environment of the site. Here, I have challenged it how I could build a comfortable house at a anonymous site with the limit.

I understood that there was advantage and disadvantage at this site beforehand. The former was that comfortable wind flow through.

The latter was a very sunless place and this town was only a house without the characteristic of the same form. So I have decided placement and a form in consideration of the small environment of such a site.

First, I placed a short and big house in the south side, and a tall and small house in the north. And a linear garden was created between two houses. This garden maintains the environment of the wind and improve sunless.

In addition, I add an angle and operate a form of a roof to take in more sunlight.

As a result, sunlight came into the room of the second floor of the high house. And the sunlight that reflected in the tall house have lighted up the linear garden and the light had an influence on the living of the south side and the bedroom of the second floor.

Additionally because it is very light even if it is such a linear garden, the living is all comfortable space with a big window of the south side and the east side.

In this way, livable space had been created by I caught small environment carefully, and designing it.

Furthermore, the scenery which consisted of the arrangement of a simple house have appeared as poetic scenery new at all so that a total facade of the East expressed it about the neighboring environment.

    I state: Sanaa style, but not as fresh as it… The atmosphere is clean and the spaces seem quiet and airy, but the overall proportions lack armony. But I doubt I could have done it better so thumbs up….!!

    I love the loft. Super-hot batten detailing.

    Yeah, the first japanese house with big windows!

    Really love it, good light, room for your own interior style, with Suppose Design the inside is so distinctive it’s hard to personalize.

    Although the inside looks fantastic, the outside looks a bit like a container.

    what’s with the sudden interest in double-house concept? This is like the fifth project..

    “This garden maintains the environment of the wind and improve sunless.”

    Can anyone try to explain that in english?

  • mjuk

    It’s great to see small houses like this on Dezeen. This wonderful little house integrates many cool features like the double-height areas and linear garden, all expressed with the attention to detail and good taste Japanese houses are renowned for.

    You cannot go wrong with white

    why this constant return to the overtly cliched and cartoonist interpretation of the pitched roof? ive got no problem with pitched roofs, but just sticking an exaggerated roof profile on a box doesnt make a building a “house”

    To Amelia:
    “This garden maintains the environment of the wind and improve sunless.”
    What the architect meant was, that by providing garden space, ventilation was maintained and daylight improved on the structure.
