Architect Jakub Szczęsny has laid out design concepts to fill in a small crack between an old tenement building and tower building in Warsaw, Poland with plans to build the world’s narrowest house, which will be 60 inches in width. Ermitage 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.
