Ever feel cramped in your own home? Think you need a little more space? It could be worse. An alley between an old tenement block and a tower block in Warsaw, Poland, will be the location for the skinniest house in the world. At just 60 inches wide, the four-story home on a diet will have a bedroom, lounge, bathroom and kitchen, stretching back nearly 40ft. Instead of the traditional staircase, each floor will be accessed by a ladder. This skinny home will take over from the world’s current official narrowest house, The Wedge, on the island of Great Cumbrae.
