Is this room the new addition or do the photos just show the furniture you want to work with?

The dining set is dramatic! It seems somewhat gothic to me. I think you are right to want to work with it. It looks special and I bet it's made very well.

I would find another spot for the console with the mirror above it, as it doesn't work well with the table and chairs. It's a bit too contemporary. It also looks to be crowding the chairs in front of it. In it's place look at some rich oil paintings about the same size as the mirror you have. The simplicity of line drawings could also work well. You could also replace the chandelier with something that compliments the style of your table and chairs better. I'm thinking wrought iron. And I see that you have some iron in you living space, so the continuity would be there.

I also think an area rich area rug that has the salmon rose colors of your chairs in it would be great. A wall color similar to that of your sofa - in the rich tan family - would also provide for more cohesiveness.

Of course you'll have to remove the other extra items in the room, such as the table (?) in the corner and what looks like a car seat (?).

Below is a rug and potential chandelier to consider to get you started.

Over the top, yes. Do you love it? If yes, exploit its differences. Put a really great contemporary fabric on the chairs. Do something unexpected, not trite. Does it have to match? SOme of us don't think so.

I did peak into the other room, and from what I can see, it does look to be of a different style than the dining room. I've seen many interiors where there is an effective mix of styles. I think it's possible here, as well.

Why yes, I do see a kids b-ball hoop. So what? Use what you love. I'd go rich and glam, something sparkly for the light. No furniture except the ornate stuff which I'm not convinced is Victorian exactly. Set it with great vintage china. Invite your friends, they're going to love it.

Paint the walls. I love this color. It is a light gray with green undertones:

Maye some kind of

Mat be gold color work better
