Architect Jakub Szczesny of Centrala has designed the world’s skinniest house/ art installation, which measures 47 inches at its widest point. Currently being assembled in Warsaw, Poland, ‘Etgar Keret’s House‘ is so narrow that it’s not considered a real building by Polish standards.

The 3 story house is situated between two buildings and it borrows electricity and receives its water from an off-the-grid plumbing system. It also features remote control stairs that can flatten against the wall when they’re not needed. The building was created for Israeli writer Etgar Keret, who will use it as a workplace when it opens next month. It will also function as a studio for invited guests including young creators and intellectualists from all over the world.
