The tv must move to over fire place if you want a sectional or any balance. You need dimensions to your posted picture but you need to float. furniture no matter what it is Sorry ugly sketch its time for Super Bowl : ) Measure up your drawing

Thank you! The tv is already mounted on the wall! :( so I'm trying to figure out how to work around it if we can. We just put so much work into the walls I'd hate to have to have to re-mud them again.

Shoot! I thought I had dimensions on there. I'll have to fix when I get back home.

You can't "work around it!" Plan first, mount tv's later : ) GOOOO Atlanta!!!

The TV HAS to move. It's in about the worst place it could be. It can go either immediately to the left of the fireplace, or on the wall at the end of the room where the piano is now. Easier to remud walls than live with an unworkable arrangement.

Let’s talk about the beams. They do not look structional. If so, remove them.

Now you have one room where space in delineated only by the fireplace.

Left side looks to be the larger. Try positioning the sofa toward the front window. Make sure you keep it in the new space. Mount the t v to the left of the window, but keep in on the console (hide wires behind). Do not hang it on the wall. On the other side of the window, you could do a desk and a mirror in the same scale as the t v and console.

This looks like the best place for the TV.

Thank you all so much for the good advice! Super appreciate it! I guess I should clarify why the TV was placed where it is: we do play video games, and the current couch/tv placement is the perfect distance for watching tv and playing video games, and it's on a swivel mount for when we have more people over.

We did consider putting it over where the piano currently is, but then we couldn't think of a good couch placement that isn't in the middle of the room.

I'm a little worried that placing the couch and everything in front of the fireplace will make the flow of traffic awkward to get in and out of the screen door onto the deck.

I really have a love/hate relationship with this room. I want it to be cozy and functional for what we do, but I also want to have some semblance of style.

What's wrong with the middle of the room for furniture placement? Houzzers highly advise keeping furniture off the walls when in the best interest of the overall usefulness of a space. Since TV is the one item that tends to dominate all furniture arrangements, it is very important to put it in the right spot (which is almost never in a corner, or over a TV and rarely that high.) Grover's plan leaves a nice traffic path behind the sofa, and if you need more seating you can add a pair of swivel chairs at the TV end of the arrangement.

Is this 12'x 18' room

Do you have another room to watch TV.....maybe you can make it a dining room or game room.

Thank you all again! I really appreciate the input! I apologize for the slow response- last week was a little overwhelming work-wise plus my phone died so I had no Houzz app to let me know there were responses.

The room is 13x20. So Grover's plan could work, but I would need to find a different place for the piano. All three walls are outside walls and the piano cannot go on an outside wall. I would also prefer the couch to face the tv so you're not walking into the room and directly into a couch. This would also create more walking space to the sliding door. With the layout as shown, that would about a 3 ft path.

So let's say the room is arranged as Grover suggests (thank you!), but with the couch and armchairs switched. What do I do with the space behind the couch if the piano can't go there? It would be about 8x13 so I could put some bookshelves I suppose, but it seems like a waste of seating space.

EDIT: I forgot to add a rather important piece of information: the internet and tv cables are all in that back corner of the room. From what I understand, it's not very possible to re-rout them to where the piano is right now due to the fireplace and door next to it.

I've seen those cable guys do some remarkable things with moving connections. That said, it appears the piano can go only where it currently is. IMO, almost anything that gets your seating into a cozy conversation group toward the center of the room would be an improvement over the current arrangement with TV and sofa in the corner. Neither of these plans is perfect--the piano constraints and that off center fireplace have seen to that--but they are better than what you have now. This one is best if the piano could go in another room.

Otherwise......this one ignores the fireplace, but gives you a reasonable conversation group. In both cases, I would make those swivel chairs.

I feel if a fire place is in the room it should be the focal point or main area of that room. In a room this size the sofa does not have to be in a corner. I think groveraxle 1st option is a great idea. You not only have the fireplace in sight but you can also enjoy watching TV in this room. The longer wall opposite the fireplace looks ideal for a bar, and the wall opposite the piano behind the sofa reading area, desk, book case or both. Good Luck. I always redesign other people's home in my mind. Since I'm no expert I never say anything about it unless they ask what I think then the flood gates open. Some have actually taken my advice on changes that would make a room more comfy and homey.
