Paint , a new light fixture that does no have edison bulbs casting yellow glow on everything some nice faux silk drapes in a color that matches the wall colr IMO choose the drapes first then match the wall color and IMO a DR fixture should light the table not the ceiling. You also need a much larger piece of art on the large wall . Make it dramatic to catch your eye as you enter Are you sure this is what was designed to be the DR it seems odd .

Yes it's definitely the dining room this setup is common in older FL homes not sure what they were thinking back then.

A rug under the table will do wonders to warm up the room.
You need art on more than one wall.
Dress your buffet. Flowers, lamps, candle sticks, bar tray...

Beautiful furniture.

When looking into the room from the perspective of the front entrance, it appears long and narrow. I think the long light fixture and the long runner accentuate that. Maybe choose a light fixture that is rounder, with some more width. That alcove at the far end of the room could be a really beautiful place to pull the eye...consider removing the art from the alcove and instead find a wallpaper you like and paper the inside. The buffet will still look great in front of it. Might be helpful to add a lamp on the buffet, too...always nice to have lighting options other than those on the ceiling. Agree that a rug will help bring some additional interest and texture into the room (and depending on size, help the room to not feel so long and narrow)...Also, an opportunity to coordinate another element with the wallpaper (as would the drapery panels).

I wouldn't add a rug since it looks like this room is also a walkway to other areas of your home, and you don't want to be walking on the edges of a rug. I would add more artwork or a very large framed mirror to the long wall, and then paint the room in a color that coordinates with your main walls but gives this space a feeling of something special.

^^that looks awesome. Love the idea of an arched mirror. He lamps look awesome!!

I love everyone's suggestions thank you so much for providing a photo @BeverlyFLADeziner now I planned on adding a very similar mirror in the space opposite the dining room. Would it be silly to have the same mirror in both places? I planned on the arch mirror and a table. I havent ordered either yet.

Different types of arches on those mirrors, take note. I would not mix them or the niche shapes

Something like this may work for your foyer. See how they used wallpaper with texture in the niche, adding a bench......some Inspiration:

Idea for dining room niche and you could add grasscloth behind mirror. Move art to wall on right.

I‘d change the chandelier. With its sight lines from hall it’s not appreciated and I think a round, lighter feeling style might be better.

You could reupholster the chairs for bigger impact, remove the table runner for a modern look and add a simple centrepiece. Hem the drapes so they only just touch the floor.

On the long wall, it’s perfect as a gallery wall.

For the niche in front hall, keep it fresh and modern and don’t fill it up.

I feel it needs a color on the walls. Maybe paint in a soft green or blue. Otherwise I like @BeverlyFLADeziner mockup.

You said you never use the dining set, so can you use the room as a small study, writing room, or sitting area?

Echo bpath's thought. Why decorate for a room that's never used?

BeverlyFLADeziner can you provide the source for the mirror you suggested in the dining room. I need that one. Thank you

Measure and then measure again to make sure the size will work for your niche.

@BeverlyFLADeziner I really like the bottom table for the entry where is it from?

@bpath my kids are younger and it's just easier for us to eat in the nook. We use the table for holidays, if we have visitors etc. I would like to graduate to using it more often when the kids aren't as messy.

We wouldn't use a sitting area/writing area either. I have a small reading area and extra room that I already don't know what to do with haha. I like to read outside or in bed or in my office.

Ultimately I want my house to look more finished instead of thrown together. We are slowly replacing young family/college furniture for more "adult" things but it's obviously costly.

The walls just look unfinished and freshly moved in. Something that can be fixed easily with art and mirror. The drapes don't work for me. They are short, thin and without volume. I'd have them go from the top window, and double width. The fabric of them doesn't need to be thick, but at least twice the amount. I think in the end it's going to look great, because the space has so much potential.

I'm still working on this room but wanted to pop in to ask what you thought of this table going in this spot. I really like the table but second guessing if it is too much.

For this spot against the wall

You'll want a table the same size as the alcove opening, or just a few inches longer. Have you measured that table? It looks fairly long.

@calidesign just seeing your response. It's long 5ft I was initially thinking 4ft but ordered it anyway. I made a new post asking for opinions. I really don't want a half moon table any suggestions?
