For starters I'd add shades to the chandelier. Bare bulbs are never attractive for dining unless they are dimmed to the point they appear tobe candlelight.

I think I'd turn the table & add a rug to anchor the room.

I'd select a canvas for over the sideboard.

Black chairs from Target

If you want a bigger table, it will have to block the pathway between the two doors. Is that OK? Do you go through the French doors often?

Large inexpensive artwork from this Etsy seller.LINK I don't love most of the prints but a few of the landscape ones are not too bad.

The OP wrote: "I love as given this dining table that’s too small and so not like the light fixture."

Do you mean you love the dining table and do not like the light fixture?

Do you want to replace everything except the buffet?

Start with a ROUND dining table 42" diameter AND new chairs.

Art over the buffet and less clutter on it, add a lamp.

Nobody understands if you like or dislike the light.

You need to show the entire porch, and the entire dimensions, a drawing,,,,,and note all walls, doors etc.

Can you turn the table the other way to give more room between it and the walls?

I am also confused by "I love as given this dining table that's too small and so not like the light fixture." If you want a different table, perhaps get one with leaves so you can expand it when you have guests.

Yes, turn the table the other way. What would work better is a longer rectangular table or a round table that expands into an oval when you have company.

Not sure why you have one wall painted black. In a tight space, paint all the walls the same. The black wall visually narrows the space. Get beautiful art over the sideboard as suggested and remove items on it as well as the small art pieces on the side wall.

Yes, put shades on the light fixture as suggested.

Get a long oblong lighting fixture once you turn your table or get a new rectangular one. If you get a round table, than keep the fixture you have.

Thank you!!!

Sorry. Spell check changed my words
What I was saying is that the buffet will stay. Everything else can go go. buffet. buffet

Wow, lisedv's proposal is awesome!!!

Love lisedv's inspiration photo. You can slipcover current chairs if that's a look you like.

for me you need some sort of rustic vintage sign to bring it out and much less intrusive scaled light fixture. I would turn the table too. I dont think a larger table is better here since you have to keep in mind the doorways and walking around

Some inspiration

I like @Celery. Visualization, Rendering images suggestion although I feel like the table/chairs should be turned the other way.

You need to post another picture with the table turned. It's too wrong this way. Does it expand? Show us the space from the buffet view. W/o dimensions of the room it's impossible to think about table size/shape.
