House for Three Children by Masato Sekiya


Japanese architect Masato Sekiya has completed a house for a family in Osaka, Japan, with raw concrete finishes inside and out.

Called House for Three Children, the three-storey house has a large window at the top on one side, from which light filters down to all levels.

A staircase on the other side leads to a roof terrace.

Photographs are by Akira Kita.

Here's a bit more information from the architect:


This house was planned for its location in Esaka, a suburb of Osaka,the biggest city in west Japan.

The occupants are young parents and their three boys.

Constructed from reinforced concrete, both exterior and interior are unfinished.

On the first floor are the master bedroom and bathroom.

On the second floor is the family room cum dining-kitchen.

The stairs area and family room are window-less, but there is a large window on the third floor through which sunlight illuminates the first floor stairs area, and second floor family room.

On the third floor is the Kids'room.

I didn't punctuate the room, but composed three multi-function Islands to serve as beds, desks and storage area for each child.

The children live and play around these pieces of furniture like fishes gathering around undersea rocks.

This is new concept for kid's rooms.

    children falling on metal grating = major ouchie. :P
    beautiful project otherwise.

  • shumuts

    looks nice, tho I would not let my kids play around in this dangerous place…….

  • Jon

    do Japanese still like Ando style? like 90’s stuff……
    but i love the furniture!

  • peemeerre

    looks like a half life scenario

  • this house is not a home.

  • m

    The beauty of a direct punch in your face. What fascinates me with Japanese architecture is the absolute lack of isolation. It really is what you see is what you get.

  • arch.kinna

    A sense of beauty always appear in the use of the precast reinforced concrete. the secrent of the monochromic environment that contrast with the colors of furniture, landscape and people!

  • Isn’t too open to live there?

    As far as I can see, I could jump from the bedroom balcony to the kitchen

  • Babu

    it’s lke a cell to me…..

  • rodger

    i like the play of the major volumes that make up this building but really, why do i see a open grill walk way over a kitchen counter? that is gross and stupid.

  • Christopher

    Very nice both inside and outside.

  • cacas

    the children will love the colors!! and the corners…and the safe stair.
    soory being ironic but I`m tired of this ego concrete houses for books…

  • Shawn

    Nice, would like more warm elements, but thats all personal taste. Like the spaces.

  • oliveg

    no warmth

  • This house for three children seems pretty child-unfriendly to me. Take those steel grating staircases for instance…
    The overall impresion is very grey, industrial and perhaps even depressing.
    I like the raw concrete finish but it feels like a bunker when applied in ‘small’ spaces.

    Raising your children in a ‘save’ environment is great but housing them in a bunker might be a little over the top.

    I dig the project but it doesn’t seem to fit to its purpose and occupants if you ask me.

    Skillfully designed, although these Tadao Ando inspired architects should have gone further by now. They’ve incorporated some 90’s high-tech in there, which is nice and matches well with the concrete.

    I don’t understand which pieces of furniture are meant to act as rocks for the children to play around. Is it those weird pine things in the 4th photo? Some of the captions don’t seem to describe the photo they are next to.

  • I really like it! But seems a little cold for children.

  • Rafel

    With these stairs, levels,… seems more for a ‘kill the children’ terror scenario.

  • Megan

    the childrens level seems unsafe as do the stairs. Made me cold looking at it.

  • Bozo

    Wish Australian builders could do concrete like that.

  • tough

    this Todo Ando reinforced concrete style is appropriate for public buildings,such as church,museum and some other “magnific” buildings.
    as living function,it’s really not a good idea.Especially living room for children.

  • Martin

    How long before at least part of the bedroom is painted pink?

  • Dariusz

    interesting spatial environment.. but I’m not loving the kind of materials they would use in prisons.. what I would love is a japanese/scandinavian architecture.. gorgeous spaces and amazing materials you can touch.. and they would be warm..

  • chung

    ah…bank gothic, a progressive’s best typographic friend

  • Tradition is incorporated into contemporary Japanese architecture.Great work

  • yrag

    It’s a decent looking parking garage.

  • Rocco

    It’s not a fun house. The kids will be in your face or in your ear all the time. Don’t like it one bit.

  • joao

    this looks like anything EXCEPT a house for a family with children.
    I wish architects didnt seem so self centered as to ignore basic common sense.
    sharp concrete edges, grate floors, catwalks and open railing.
    this is an invitation for disaster.

  • elsee

    This stereotype somehow does not evoke the sense of three children – it excludes more than being inclusive – the reductive thoughts of modernism brought about by the world wars of the last century – have ended up becoming stylistic statements rather than being a more humane architectural expression – of humanity and nature –
