I'd use two peices of art placed vertically at the top of the landing, so you are looking at it as you come up the stairs. Leave the side walls bare. Or one long vertical pieceor art if you can find something interesting.

Thank you for the suggestions. You’re right about the lightning it would have been nice if the builder included lights because the staircase is very dark. I would look into finding one big art or two vertical pieces ..

You can have the recessed light turned into a light fixture, for a ceiling mount or semi flush light. It would add some style, but you'll want to make sure the light is bright enough.

What's your overall decorating style?

Great idea about the recessed lightning I didn’t even think about changing it.
My overall decorating style is non existent lol… I don’t have a decorating bone in my body . If I had to choose Base on my decor now I would say farmhouse.
My color scheme is gray and teal throughout the house and most of my furniture throughout is that dark gray weathered look and all the floors are farm hardwood and the wall is Sherwin Williams light French gray.. so a true gray with bo undertones.. hope that helps!! Thank you all for the suggestions.. keep them rolling ☺️

Add some texture and light. This might be too weathered for you, but shiplap could work and be the "modern farmhouse" look

That’s nice I like the shiplap and the light fixture idea.. my stairwell is literally tall and skinny as pictured.

You definitely need a good source of light for whatever you put on there. We had a skylight in a similar stair well and it was wonderful. But a nice light like Nicole B pictured, or some long light fixtures running on both sides of the tall wall will do. In terms of decorations, we've had a tall tapestry on one wall, a mirror with a small shelf above the landing or, in another home with this problem, we made a gallery of family pictures, eye level as you walk the stairs, on either side wall, and continued on the wall facing the stairs.
