jennifer, if you want to do a slat wood wall (there are a lot of tutorials on how to do it. it's mainly 1x1 or 1x2 wood 'sticks' that are 8'-10' tall. you could use fir and stain them. or you could paint them black. or, if you have a bigger budget, get walnut or something similar. walnut you'd only have to oil. it's a red wood. just a medium brown tone that would great w/the floors. if you like a more natural color, look at 1x2 white oak pieces. (any lumber place should have them) a satin oil finish is all you would need. those can also be stained a walnut color. (oak is cheaper than natural walnut this one is actually poplar that they painted. if you're goign to paint, use poplar wood https://brepurposed.porch.com/2020/01/20/diy-wood-slat-walls/ so, you'd paint the wall black, and attatch the slats. this looks like Alder that has been stained a darker walnut stain. here's the lighter stain color. you could also get plywood and rip it to 1" pieces (however, plywood and lumber have skyrocketed this last year. it's ridiculous what a sheet of plywood costs.) https://simplyalignedhome.com/affordable-slat-wall/ I think if you even did the entry niche w/some type of slat or design would look great I'd go all the way down, and prop paint it black, or do the wall in black and do walnut wood pieces. or, I like this too. find a cool black/white/gray piece of art, something more vertical, and hang it. bring in some bright color stools to fit under the marble. bring in a entry way rug that matches or make a cool design and use that as your art element in the niche (I actually made a headboard similar to this one out of scrap wood pieces. came out really cool) over on the dining wall, you could easily do a living plant wall

I have a big empy wall and I don't know how to decorate. I was thinking about a big mirror. Any ideas. Please. 😊🤔🤔

Thanks for the ideas ! I have this art piece above the buffet now, but I am looking for a bigger rug that goes well with it... any ideas of what style I should get for the rug? Thanks again !!!!

I think a couch that has less depth would work wonders in this space. You have a very narrow field to work with, albeit still doable. It might help to mount the TV, otherwise get a thinner console. Sectionals are usually unnecessary but if you plan to keep something similar, a sectional like this would work well. It has less bulk than your current couch and the sleek lines help to divide the room from the entrance.
