If you prefer a console, consider one that is about 2/3 the width of the wall to better fit the space. Then a large artwork placed above. Perhaps there's space on the right for a nice tall indoor plant in a decorative tall pot. Is there lighting above the dining table that could compliment the space?

Needs a longer console; perhaps something painted, or something textural. Then it needs a very substantial piece of art above.

The question then is.........do you need storage or not? Easier for length, ( 80 inches + with no closed storage.

The 20" ceiling height is irrelevant. Pretend it is nine feet. You design at eye level and a bit above.

You dine sitting down : )

Adding some colorful art might be nice too.

If you don’t have young children, I try a rug with color and pattern.

How about a chandelier in the mix?

Thank you so much everyone for your suggestions! I appreciate you all! Jan Moyer, where are the consoles you suggested from? I’m loving the simplicity of the 1st two you posted. Do you think a natural wood color would go with the grey wash table? And yes, I agree with the rug and chandelier suggestion as well. Just have to find one for the extra tall ceiling which is hard. Elcieg thanks for the link! Very helpful!

Jackowskib, any other suggestions other than a console table? We don’t have a console table but I can’t think of anything else to put there other than artwork or a huge mirror. Would love other ideas. Thank you!

Saw a room area similar to that by Candice Olsen years ago....long console with lamps, plants etc, then three plain tall mirrors horizontally above the console. Stunning and simple.

wall shelves same wood as your dining table.

You should broaden your selection of sideboards. A painted one might be a good option.

WAYFAIR!!

Love the simplicity of the console Jan shared. Goes with the lines of your dining table.

Console table will not anchor that wall. It’s lighter in scale than the dining table. The wall needs a cabinet

From the look of the table and chairs and floor you like more of a monochromatic look. I would look for a buffet with tall legs or a wall hung cabinet wider than the one you tried. In the color of the chair upholstery, or chair legs. Wall hung will give you more floor space visually and I would hang it a bit higher than a normal buffet. If you wanted to bring some color in, rug and artwork. I like the idea of sconces also. Your table is blocky, chairs are solid, maybe some iron sconces and a cabinet with some texture or carving to it for some interest. Depending on what it reflects, an interesting shaped mirror would add some uniqueness. Just depends on your decorating style. I actually love the serenity of your space. What does your kitchen and living room look like? Not that everything has to match, design wise, but it's nice to have a good flow. Then a fabulous chandelier to top it off!

The wall really doesn't need a cabinet"

It seems to need a vignette. Starting with a long enough piece, even ore important than closed up and weighty, along with a very substantial piece of art.

That alone is enough to kill the sense of empty and a bit "yawn" : )

Her table and chairs provide plenty of mass ( in a good way) .....no need for more. She seems to love a pale wood monochromatic feel? Live dangerously...add color in art.

Thanks so much everyone for your valued and much appreciated advice! We did this to it to give the sideboard/buffet table a chance. We added the collage of our travels. Still undecided about that sideboard though. Any suggestions?

The sideboard is fine.

I don't love what's above! Why? I have nothing against collected , meaningful art or photography. They are best LARGE or where they can be viewed up close.

For a diner at the table? They are too small. And they INVITE you to clutter the top of the sideboard. They leave YOU wanting more! What you need is less... with stronger size and scale.: )

Perhaps another good spot for the travel pics?

Thanks Jan! I really appreciate your honesty and viewpoint! I will look for larger scale art to better fill the room.

Definitley add a chandelier--it will accent (and fill in) your tall ceilings--plus the console or sideboard with wall decoration above.
