The concept of the cube hotel first emerged in Spain, and has grown in popularity in recent years to spread to many diverse corners of the world, from the Swedish Lapland to the Australian Outback and the coast of Thailand. Each hotel room occupies a cubic block and is typically situated in a picturesque location, boasting panoramic views through the floor-to-ceiling windows.
