Can you get rid of any of the actual doors? Not the openings, just the doors.

Ye, we could remove the interior doors, just not the one on the left since it's exterior.

Can you post images of your current furniture in the room, from different angles? It will help to visualize the space...

Since art is very subjective, it should be art you enjoy as it is the first thing you will see when you enter. Keep the art over the buffet server as large as possible. Don't do a "grouping" as in a small room it's better to keep less items but big and functional.

Art inspiration for over the buffet server:

On the left of the entrance door: a small table, cabinet, not more than 30" wide. It could be a wall hung shelf with a basket for mail underneath. Instead of a lamp on the table, consider a wall sconce as you walk into the room. I would have the sconce on the left side of the console so that it can create a soft light for that cup of tea late at night.

I need to see the space and have a lot more info as to how many seats your style really how can we help without any context. IMO a very small DR and certainly not space for 1/2 of what has been shown. I do agree remove the doors thet you can for sure to give you a bit more space .BTW I hate banquette seating in any DR it is a PITA to get in and out of and honestly saves very little space and always looks like a kitchen space .

One thing that you could consider is the historic "Formal" furniture arrangement from the 18th and 19th century. This means exactly the opposite of what you would think. The formal furniture arrangement kept furniture like the dining room table closed and broken down into its parts and pushed to the wall unless it was going to be used for a large dinner. This is why so many tables were gateleg + flip up combinations.

Maybe what would work best is some sort of gateleg table that could be kept folded down and either kept in the middle of the room or put to one side, and a decorative semi flush fixture you could walk under rather than a chandelier.

My very small house has a room inside the front door that is shown as "dining room" on the plan, but really acts as an entry, since there is just one way into the house. It can't practically be set up as a formal dining room at all times, sometimes it has a bike or things like that in it. (We live right on the street in an urban environment and the bike would either need to be muscled down into the basement or carried through the living room into the enclosed yard.

It can be set up as a dining area but usually the room is kept pretty empty with a gateleg against the wall and a few chairs, but it can be set up as a full dining room as needed.

The rooms that some of these tables were used in were large enough to keep the tables set up, and some of these tables can be set up to be 30 or more feet long. But the idea is the same, they are usually broken down into components.

Just a note: Designing NYC apartments, and now LA, for many years, it's all about scale and function both in large and the smallest places. Banquettes save enormous space and are very comfortable and allow additional seating in smaller spaces. These days, now that we are working out of our homes, it's nice to have seating other than dining chairs. I would sit in the corner on the banquette for all those hours!

It seems your home is not large and needs to be used to capacity. As mentioned, you don't need to remove doors, although the kitchen door removed is practical.

Your dining room can accommodate all the furniture and the layout with no problem, and still allow easy access to all the other doorways. Keep the "decorations" (art, accessories) to a minimum, while still enveloping your style. I can't wait to see what you do!

You need to take the comments (including mine), on here, with a grain of salt. These are just suggestions, and hope it helps with your Design Dilemma. As a design professional, this would be my solution. If you have any questions, please don't hesitate to ask or comment. Love helping!
