Consider a wallpaper with some pizzazz.

Dark Blue Chinoiserie Wallpapered Dinng Room · More Info

I would be careful with a dark wallpaper in such a small space , it can be quite lovely but IMO that room has some nice natural light so i would tend to keep the space light. As for storage I think I see a bakers rack in the bottom right corner maybe replace that with abuffet instead of tall things taking up space visually and get a great piece of art on that right wall and maybe some pretty light colored drapes for evening privacy maybe in faux silk and a color close to the wall color which BTW seems pretty boring if that could be changed it might be part of the answer.

Bookcases and shelves can tend to clutter a room faster than most anything.

Look for under bed storage boxes. Ways to maximize storage in closets.

Drapes would frame the window and give color to your room.

Add a large framed print to the biggest wall.

I don't see any place in that room to add storage with that table in the middle. If that's what you need, you first need a narrower table.

I'd keep the dining area pretty bare and concentrate on creating a view out that window. Here's a sideboard with sliding doors that's only 13" deep.

Narrower table - the width of 3 of the glass panes. A low storage bench, wall-to-wall, under the window. Tall drapes, much bigger fancy chandelier. Go for the Parisian pied-de-terre look...fabulous window, great proportions.

Would turning the table the other way give you more room?

Yes, I'm also wondering if you turned the table; would that give you more room for a buffet?

I'd do drapes high and wide,just covering the inside of the window when open. Possibly the table turned would work better. Maybe use a storage bench for seating. There are narrower pieces of furniture than that baker's rack, but it depends what you need to store. I don't have enough of a bead on the whole space (and the dimensions) to give better advice. But I love the transom over the door!

I agree, not enough room for much other than the table + chairs.

You can find very narrow tables for help in serving. This is 8" deep.

This one is from Target. 33" x 33" I think it's around $60. I've seen it at the store and it looks really pretty good esp. for that price and the fact that it has a thin frame so it looks more finished.

The other is from West Elm so more expensive for sure.

If you decide to go with console, get traditional one coz your dining room set is traditional. Leelee's console is more modern .

First its important to know and see the rest of the home looks like Everything needs to be coordinated properly.

As an observation there needs to be a fresh coat of paint preferably in an off white . Window treatments added and Fabulous piece of art/painting to add color and life to your space. In as much as storage is needed be careful not to clutter the space.

Consider corner cabinets next to the window. They can hold a lot of stuff, but don't take up needed floor space because they occupy just the corner, not where you want to walk or place a chair. The following link has some interesting ideas plus a thoughtful discussion about how to select one. Your might want windows in the top to display favorite dishes or glassware, or to have the cabinet enclosed for more random storage.
