Beautiful space. I would start looking at pictures. These are not your style, but different ways you could arrange furniture.

The floor plan should show the placement of the piers (square columns) so that they can be worked around. Are there three or four of them?

You need to break the room up into several seating areas. You will also need to add textiles for that "cozy" feel, rugs, curtains, etc. Also, keep the focus of the room down low, which means not installing any light fixtures too high. And be careful about installing the TV too high for comfort and optimum viewing.

Love your home and the story that goes with it. Fabulous space with lots of natural light.

Couple of questions.

1. Is the double french door your front door?

2. Preferably keep the TV on the wall between the columns and not over the fireplace.

I'm having a hard time identifying this space in your photos. And good, no need to put a TV over that fabulous stone fireplace. It looks like it is almost large enough to stand up in it? I had a house that was originally a hunting lodge than a dance hall and it's main fireplace you could stand up in! So that's why I'm asking.

3. Would you mind posting photos of your dining area. As you stated that area is taken care of but it would help us get a visual as to your style and even though you don't have an open concept you still want the areas to have some relationship to each other.

4. Do you have any ideas of what you want to do with the fireplace once the paneling is removed?

5. What else do you visualize this room to be used for besides TV watching? Is a very large pool table a consideration?

Can you post a room layout with all measurements, including doors, windows, and posts/piers, and also show on that picture where you envision the TV placement?

Way too big a room for only one seating area. Decide how you want to use the room, e.g., tv watching, reading, conversation, crafting, playing board games or cards, etc, and that will help you organize the different areas and dictate to some extent the furniture needed. Use rugs to ground the different zones and add appropriate lighting to each area. Look at tons of Houzz photos to get ideas for how to organize and layout multiple seating areas in a single room. We have two seating areas in our large living room and one area is for TV watching and reading while the other is for conversation. The conversation area comprised of 4 very comfy chairs around a round low table is a surprising well used area both for guests as well as for just my husband and I when we want to chat. Good luck!

Oh my golly, wonderful light! So many possibilities. Art studio, loom room, library corner,. What do you envision doing in this room? My granddaughter’s dance teacher would swoon.

A giant rug in the center would be a good be a good way to ground the center seating area. Then two "reading nooks" in the back two corners. Do you have any children? What type of things do you envision going in your living room? Other entertainment? bar area? storage?

Thomas, how many people live in the house, and how would you use this room besides TV watching?

Just want to say you have a beautiful home!

Maybe an arrangement like this could be a jumping-off point for you. There are limitations as to how far a TV can be from your seating and still see comfortably. I don't think you can hope to place the TV on the wall. Do you have an outlet in the floor?

This is a pretty big project for people who declare themselves helpless. You might want to temporarily pick up some discarded sofas and chairs from the local Salvation Army or church resale shop and see what actually fits in your space well. 90" sofas or larger will not be an issue. Your problem may be selecting items that are too small in scale for the room. Measure, measure!

TV lift for center of the room.

You could build a half wall with your columns and place the TV and electric there See below I would paint the trusses white to minimize their effect.

This space is huge and you need to position furniture so it defines separate areas. There are at least three large areas. The fireplace area should be for conversation or for relaxing. A U-shaped arrangement of sofa and chairs or loveseats, facing or flanking the fireplace. Put your TV on the wall in the bottom left area of your drawing. This should keep glare to a minimum. Beverly's note on TV size and viewing distance should be heeded. Strangely, you have to sit closer with 4K TVs than you do with 1080p TVs. This might be a good place for a sectional, recliner(s) or a chaise. The last large area is full of windows and light. Maybe a good place for a game table, or even a piano. You have the room for it.

mindshift you forgot the columns in the room.

Plenty of room for a pool table too!

Are you retired, grandparents? What activities would your granchildren like to do? You certainly have room for any and all indoor entertainment. I'm adding some inspopix for you. Think of it as a contemporary lodge and look at these for furniture and gathering ideas, not so much for the architecture. Of course, the area by the door (between the bay windows) will be your foyer.A round foyer table with a nice floral arrangement would be pretty there. I agree with TV area between the columns on the long wall, and would add a reading nook at the bay window there. I've crudely mapped out my zoning plan so you can see where these groupings would go. Sorry I haven't got the technique down for writing with the mouse.

Cozy classic furniture grouping around the magnificent fireplace.

A more neutral color palette.

Certainly not this style, but a pool table centered in the space.

Don't forget a game table; maybe by one of the bay windows

I’ll reiterate what everyone else is basically saying...you’ve got to stop thinking of this space in terms of it being one room with one seating area that has one function. It’s like 5 rooms but without the walls separating them.

This is a good problem to have. As others have suggested break the room up into several areas of function. Also, adding some interior partitions isn't out of the question. The room could be divided up some with full or partial height partitions.

I would make it in to 2 rooms !

Rugs are important to delineate the spaces.

I chose to use 2.

One end is to enjoy the fireplace. I used two large sofas and each sofa got its own coffee table.

In my inspiration photo you can see how two more chairs can be added to face fireplace.

The other end I put a game table.

I would keep the furniture in toward the center of the room. Don't place any piece up against the wall unless you want a large media piece by the game table, opposite the fireplace.

I agree with several of the Houzzers ideas previously presented that suggested 3, 4 or more spaces within that large room:

Here are the suggestions

1. TV viewing area

2. conversation area: one large one with two sofas plus two chairs, and perhaps a second smaller conversation space further away with two comfy chairs and a side table between them

3. music space

4. library (this can also be the smaller conversation space mentioned in 2. above) or a more serious homework space if you place a table there to work on and have plenty of outlets and wifi connectivity cabability

4.game area with table (for cards, chess, etc) or pool table or ping pong or whatever is your kind of game

5. a tea cart

6. a wet bar

I like the image of a lodge lobby, or the first floor of an old-fashioned dormitory where we did our entertaining because no one was allowed up in the rooms.
