A hallway in my mind always leads to a great visual- it could be leading to another room or have an arresting artwork at the end. You eye needs to be able to go down the hallway and stop at something beautiful
This hallway leads to a colourful green console table with interesting display. The runner already tells you that this is going to be a colourful space.
This one here has a great piece of lighting that is a very strong visual.
Or you can use it as a place to build a bookshelf, especially if it is very long. It is a very good use of space.
