Polish architect Jakub Szczesny claims to have built the worlds narrowest house, just 122 centimetres across.
The house has no windows, instead, a perforated steel facade is used to allow in light.
Keret House is to contradict that false image, simultaneously broadening the concept of impossible architecture.
We deeply believe it will become a symbol of modern Warsaw ingrained in its complicated history.
The House attracts attention of media from entire world.
The house will remain in place for at least two years, but could end up staying for good.
It has already become a Warsaw icon and is already on the tourist map, said the architect.
A trap door leads to the staircase entrance below from the living area of the Keret House.
