Considered the world’s narrowest house, the Jakub Szczesny-designed home of Israeli author Edgar Keret has opened in Warsaw. Located in an ‘appealing cushion of air’ between a pre-war residential building and an 11-storey post-war housing tower, the new home is 4ft at its widest point and 28inches at the narrowest.

The house will be used by Keret on his twice-yearly trips to Poland and includes a small kitchen, bathroom, sleeping facilities and workspace accessible by a series of ladders. Of his inspiration, Szczesny said: “I fell in love with a space between two buildings from different periods. I decided to make a link.”
