How do you turn a small space into a huge cash cow? Fill it with the most claustrophobic living quarters imaginable, call its lack of width a feature, then rent it out to artists as a living/workspace. That's just what architect Jakub Szczesny and team are doing with the skinny space between an old tenement block and a tower block in Warsaw, Poland. The design allows for a bedroom, lounge, bathroom and kitchen within the tiny space, all accessible by ladder. Read more about to Warsaw design and other skinny houses on Daily Mail. Link
