It is good when the area of the hallway is large enough, because in this case you can afford any design of the hallway, any decorative and furniture delights. Unfortunately, even the average size for most halls is a luxury that not everyone can afford.
The main principle that you should adhere to the design of a narrow hallway is minimalism, the room will look better, the less diverse details in it will be. A tiny hallway will acquire a cluttered look if it is filled with decorative vases, stands, napkins.
As for furniture for a small hallway, it should not be bulky, for example, to place outerwear, you have enough cabinet only 45 cm deep. If you like non -standard solutions, then you can combine a cabinet with an interior partition. The problem of lack of space will successfully solve corner cabinets.
If you look at the design of the hallway photo, you can notice that mirrors are almost always used, and this is not surprising, because such a simple technique will significantly visually expand the space. There are many mirrors installation options, they can have a small size and be hinged, you can install one large floor mirror (this option is unacceptable for families with young children and animals).
Growds, shoes and fakes will help to avoid a mess in a small hallway. If there is no space for installing a nightstand or chest of drawers, then you can buy a small shelf.
As for color design, withstand it in light colors.
