Floor plan design single-family house with around 150 m²

No, I put so much work into it and now I want to live in it. I'm trying to improve the living room with decorations, curtains, lighting, etc., and I can imagine that changes a lot. Maybe it's not particularly "open" to the outside, but maybe less oppressive and bare and just cozy.

I'll try. Friends of ours have practically shut themselves in. Even the idea that someone might randomly look inside is disgusting to them. I feel a bit trapped there, but the room is very cozy. I even think it has about the same windows as your open-plan room. Curtains, pictures, wall unit, dining table, carpet, flowers—nothing special.

Naked and white cannot help but appear ba(re)(c)old. I don't want to look for the resell thread here, but rather quote Nina Ruge: everything will be fine.

We want to replace the current sofa with a corner sofa, whose backrest then reaches to the west window. Finally, with a footstool that would then be under the west window.

I don’t see that at all here. I see a 3-seater or something with a footrest or large ottoman. And that on the west wall with the canapé on the right side.
A corner sofa would be too cramped in the corner and wouldn’t add anything to the room. Are you on FB? If yes, then I can recommend some furnishing groups there.

Yes, could be, but then half of the people would be looking towards the hallway and not out the window, which is a bit of a pity?

Why should they look? That’s nonsense. My guests talk to each other and my view and my furniture don’t matter at all. That’s the mistake everyone makes: everyone looks at the pimple on my nose, and when you ask, it’s like: what pimple?…

What advantage does putting it crosswise have?

Crosswise stops, straight faces it.
It’s just different, and why haven’t you tried it yet before asking the question? It’s done in 2 minutes.

We deliberately placed the window in front of the table so that you can always look out there

What do you keep looking at there? We go into the garden, and if we look, then preferably right in front of the window or island.
You eat or do crafts at the table, you don’t look out.
Have you already planted your bush on the west wall?

Are you on FB? If yes, then I can recommend a few furnishing groups to you there.

How can one find them? I would also like some tips.

I don’t see that at all. I see a 3-seater or so with a footrest or large ottoman. And on the west wall with the canapé on the right side. A corner sofa would be too squeezed into the corner and gives the room nothing. Are you on FB? If yes, then I can recommend some furnishing groups to you there.

On the west wall and not on the south wall as before? Then you are constantly looking into the long room; wouldn’t it be more sensible to have the “short” view? (like before, see outline)? I thought with the corner sofa I was hitting two things: - “short” view and to the TV - “long” view and even out of the window (see arrow)

Why should they look? That’s nonsense. My guests chat and my view and my furniture are completely irrelevant. That’s the mistake everyone makes: everyone looks at my pimple on my nose, and if you ask, they say: what pimple?...

Well, we and our guests have always liked looking outside while eating, it’s nice when you have a garden in front of you. But I think both work and you can just try it. I think in terms of space it won’t make much difference either way.

Have you already planted your bush on the west wall?

No, first the gardener has to come and level the ground a bit. I think otherwise the bush would quickly be gone again. But in spring then.

Are you on FB? If yes, then I can recommend a few furnishing groups to you there.

I am and would be happy if you could tell me.
