World’s narrowest house, built in a narrow space between a pre-war house and a modern apartment block in downtown Warsaw, was officially launched on October 20.

The two-story aluminum and plastic house, which has a floor area of 14 square meters has been built by a Polish architect Jakub Szczesny. Sunlight comes in through the holes in the bedroom, as there is no room for windows. Instead of a staircase, there is only a ladder to go up and down.

For the next year the house will be occupied by Etgar Keret, an Israeli writer whose ancestors died in Poland during the Holocaust. Later, other artists will be invited to live and work in the building considered to be an artistic installation.

The house is located in the Wola district between Zelazna 74 and Chlodna 22 streets, and has been named after the first tenant - Keret.
