The designer Jakub Szczęsny from Centrala designed the world’s thinnest house named as Keret house.This beautiful peice of art has been embedded in the crack between two buuildings and claimed to be the narrowest house in the Warsaw,Poland. The interior will vary between 122 to 72 centimeters on the narrowest spot.It’s not just a house in-fact it can be used as as a studio for invited guests, intellectualists, and young creators from all over the world.According to tuvie ”The main feature of this house that we consider as “very cool” is the stairs. It looks like a “pull down stairs” that you usually use to access the attic but these stairs can be operated with a remote control to invite the guests to come up. When in closed position, these stairs can flatten themselves”.
