I would choose option 2 with a small sofa on the window wall. Then you still block one window, but many people don’t like that you can walk behind you. So many don’t like this unprotected feeling. Maybe you can also counter this feeling with an almost ceiling-high room divider and still keep the window free.
I have to say that I am a home cinema enthusiast and positioning the TV as in options 1 or 2 would not be an option. On the one hand, backlight must be avoided (although you could shade here), on the other hand, you couldn’t get a proper front speaker alignment with a symmetrical image. No no, you really need a nice wall to place it. The fact that the rear speakers get an asymmetric sound image through the open side isn’t that bad, since a diffuse sound image in the rear area is desired anyway in home cinema.
With all 3 options it’s tight at the balcony door when the table is occupied.
Don’t you have a lowboard, shelf, DVD collection, games, hobby stuff that needs to go into the living room?
I would take option 3 with smaller upholstered furniture.
With the TV between the windows you often have the problem of glare, unless you have a north-facing orientation. Maybe you are limited by the size. Those things are getting bigger and bigger. Some of the pieces hanging on the walls are really huge.
I don’t like a sofa in front of floor-to-ceiling windows at all. I don’t find it visually appealing, I don’t feel comfortable, and it somehow takes away the light and openness the windows are supposed to bring.
Option 2 would not come into my house. You build such beautiful windows to the garden and then just stare at a wall from the sofa!
With option 1 the TV will probably be very small, so presumably option 3 as a compromise. It depends on how important watching TV is to you.
I would also find option 3 best. For my taste, however, the dining table is still too much in the kitchen. In general, I find the room too "open" — but that’s just a matter of taste. I’m more of a cave person anyway.
With option 3, I would definitely mount the TV on a swivel arm so that it can be positioned as needed for a good view from all couch seats. We have that too and it’s great.
Are any other pieces of furniture planned or will it all stay that "clean"? Bookshelves? Dressers? Sideboards? Personally, I somehow miss an optical separation — you enter the room and everything is open, a bit like in the furniture showroom at the store. Mentally: You enter the room, on the right you look over the couch, on the left you have the kitchen in view. In between somehow the dining table. But as they say: For those who like it, it’s the best.
Therefore another question: How do you currently live? Open kitchen? Size proportions? Will the new living area be bigger or smaller? Which furniture is to be accommodated?
We currently live in a rental apartment. We have a living room (21m2) as a passage room and a kitchen (14m2) as a closed kitchen. In the apartment before, I had a living room wall unit, and now only the TV on a
rollable small table. We now watch TV almost exclusively in the bedroom, since our daughter is still small. And since the living room is a passage room, we don’t want to disturb her in the evening with the TV. I still want to have a TV (possibly speakers) in the living room. Eventually the daughter will be grown, will also have friends, and they will probably want to watch TV too.
