You can do this using a floor covering.

Narrow and long rooms are recommended to be divided into two parts — hall and entrance. You can do this using a floor covering. For example, at the entrance, that is, near the door, you can put linoleum, laminate or tiles on the floor, and the second part is covered with parquet or carpet. If the height of the room allows, then the hall and entrance can be divided using different floor levels. It will be appropriate to install a pair of sofits above the front door. Happy owners of large front ones have the opportunity to install here not only a wardrobe, but also a vacation chair, and a mirror with an ottoman.
