The hallway is a very specific place. On the one hand, it plays a representative role and is responsible for the so-called first impression. On the other hand, it is the least important among all domestic rooms, as it is only temporary. In most flats it is a zone developed at the expense of rooms or kitchens, often disproportionate and difficult to develop. The wallpaper for the hallway, however, creates a wide range of possibilities for climate change in this place.
