In Warsaw, in the district of Wola lies a small crack of space between the buildings on 22 Chłodna Street and 74 Żelazna Street.  Jakub Szczęsny of Centrala, recognized the potential to create something unique within this narrow area, and derived a design of an art installation entitled Keret House. The house upon completion shall become the narrowest house in Warsaw, measuring an interior that will vary between 122 centimeters and 72 centimeters in its narrowest spot.

The house will be a workplace, a hermitage created for an outstanding Isreali writer, Etgar Keret. Besides, it will also fulfill a function of a studio for invited guests – young creators and intellectualists from all over the world.

The residential program, conducted in the heart of Wola, is supposed to produce creative work conditions and become a significant platform for world intellectual exchange.


Structurally the house is a simple tri-dimensional steel frame finished with plywood, insulated sandwich panels and styrofoam covered with concrete cloth painted white.

The interior will also be painted all white.

The “living” will place itself on the transformable, remote control openable stairs, that flatten themselves when being in”up” position and become regular stairs when going down.

It will be equipped with boat-inspired water and sewage technology independent from city systems, the electricity will be delivered by a neighboring building.


Currently the house is receiving building permits as art installation, since it doesn’t fulfill any existing Polish building codes, the building process is supposed to start in September.

    Haha. Love it. Living in the width of a staircase.

    • Tim Doogan

      Width of a staircase? If that’s not motivation to eat healthy and stay active, I don’t know what is.

      But what’s the test result will be :)?

    There could be more windows

  • Tengo Alaverdashvili

    Like it

    A novel concept, but why a triangular section? A rectangular section makes no difference to the street elevation, and just think of the possibilities; you could get in a glorious 122cm wide bath in that top corner, or some equally jarring juxtaposition of public and private relationships…

    • Ronia

      good point :)

    • Fausto Briosa

      Man… the plot is triangular, there’s no more space there for the house to be rectangular!

      Look at the plans!

    • Hannah

      Probably because the house will be sitting on a tripod that needs to be placed where it is under the large part of the triangle to hold up the majority of the weight and so that the stairs can open. notice there is not much weight being held up on the right side, in proportion the the left.

    with a small earthquake the guys inside may become 2d. really, the space is more like a seismic joint!

    still love it!

    • Jeremy

      Earthquakes in region of Warsaw are quite rare. ;)

    • Dougie Fresh

      Very earthquake unfriendly… Also you can tell that those buildings have shifted towards one another over time, its only a matter of time until the structure is slowly crushed between them… Likely a very long time though..

      Also, what about a fire escape route?

      • Jenious

        No you can’t and no it won’t. They are perfectly straight, photos have angular distortion.

        How many times in your life have you seen a huge building leaning on another? That’s what I thought.

  • Patryn Hyeronimus

    don”t like at all for an architectural piece. but for a piece of art …why not , still don’t like , but art is art.

    In fact i cannot stop myself to see bad conceptions in this project .

    I think it is a good point of research for spaceman home in orbit . but that’s all.
