Floor plan design single-family house with around 150 m²

That would work! However, the TV is not just a TV board, but there is also a bookshelf that I don't want to do without - TV + bookshelf have a width of about 2.4m (each 1.2m) - so the TV would have to be (partially) under the window...

Do all the books have to be in the living room? Acquaintances have attached a long bookshelf high above the couch on one wall, where dozens of books fit. And it doesn't look bad. You could also install something like that above the couch (of course where there are no windows) and above the location of the piano. And the books you use less often could then go with the old bookshelf into the guest room.

I focused too much on the inside of the living room and I thought the window sides would work by themselves.. :-(

I think I’m in a movie... I’m having déjà vu!
We had the same endless discussion about the fireplace and the wardrobe back then. You should plan the windows, you never addressed that.
Yes, I skimmed the beginnings of this thread because this sentence annoys me so much, since we have now been on one topic for a week, namely building you up and accepting things as they are or changing them positively.
Instead of enthusiastically approaching the matter here (I would already have been to Ikea a long time ago and would have bought a big rug or a TV board and presented photos here), you are still licking your wounds and focusing on something completely irrelevant, namely the outside corner.

Since when have you been in the house? Since October? You have only experienced the dark season so far...

I just stick to it that much. But if it doesn’t work otherwise, a nice place will be found in another room.

Honestly, I don’t find that particularly chic or decorative either. How wide is the piano?

I really like the suggestions here and will definitely implement some of them. I see myself that it doesn’t look great currently and that something needs to be done differently.

örgh.... really like... will definitely...
So, you mean you won’t, right?!

That’s true, that’s why I need help with that too.

Then let yourself be helped

Now practice the second step: accept the suggestions. I still have the feeling you try to find a counterargument for every suggestion. That doesn’t help you move forward. Again, the suggestion to maybe get a professional who supports you.

That’s what I also read from it.

I would always furnish the living room just as a cozy room for the family that maybe guests can also enter. The guest area is preferably the table / kitchen.

That’s also how it is for us: a mega sofa, but guests don’t sit there at all. I once bought two small stools like that, they can be placed anywhere. And a box that can be used as a bench. But none of it is used because they want to be sociable around the dining table. However, you also have to acknowledge how often such a group comes together.

(Where) have these already been seen here?

I think in the house pictures thread. In combination with the kitchen. So it could possibly also be in the kitchen pictures thread... Hm. Black metal chairs with geometric patterns. Could also be total nonsense and I'm mixing up people now.

I also don't like sitting as a guest in those huge L-shaped sofas. They are too deep for me and I think they dominate the room's proportions (not always nicely). I would make the TV mobile so it can be rolled away and place the piano where you want it. And then really furnish in small pieces—2-seater sofa, 1 or 2 single seats in a nice design, an elegant shelf on the wall, the piano, and plants. Plants do a lot of good and create atmosphere.

These are the Forest armchairs from Fast; not a geometric pattern, but stylized trees (hence forest); actually an outdoor chair:



(not all chairs have a fur cover yet)

How wide is the piano?

As a rule, 140cm + 5-10 cm, depending on the design
