So first of all... it is your (your) house. That means you have to build it the way you like it. That’s why I can only give you my opinion when I look at the floor plan. The opinions you get here are usually quite objective. Because no one knows you and basically no one cares how you build. Maybe a little subjective, if personal experiences and one’s own floor plan mentally influence it. And you see, there are different opinions. At the moment, I just think you are deceiving yourself a little because you have already drawn in an unrealistic furnishing in the living room.
3.8 is okay in depth for a living room. But not more than that. It’s okay when you put an L-sofa on the left side of the plan. The way you have furnished it doesn’t work at all. By the way, I currently have 3.7 m in depth myself, so I can estimate the measurement well.
Mistake 1 that is often made: sofas are placed directly against the wall. Do you do that? Apart from the fact that you shouldn’t do it because of ventilation behind, it also looks weird. So move the sofa 15-20 cm away from the wall.
Mistake 2: the sofa dimensions are unrealistic. I haven’t measured it exactly for you, but it looks very small. Now of course it depends on the sofa, but a sofa is about 90 cm deep. Some centimeters less gladly, but sometimes more if there is some adjustable headrest, etc. included. The same naturally applies for width. Often 2-seaters are drawn as 1.50 m or 3-seaters as 2 m in the plan. With armrests I would calculate about 2 m for a 2-seater.
So now add it up.
Wall distance 0.2
Sofa 1 depth 0.9
Sofa 2 width 2
Sum 3.1 m
Now you have 70 cm left. That’s where your TV bench comes. If it has a drawer or even doors, depending on the depth of the bench, it can get quite tight.
With a coffee table it also gets tight.
For me 3.8 m in furnishing is not deep enough. Does it work? Maybe just barely.
Furthermore, there is no window in the living room. Yes, a large terrace door at the bottom of the plan. But that is far away and doesn’t really feel like part of the living room anymore. There are floor plans where the dining table would still be there.
Where I now agree with , I don’t know your priorities. If the living room is not important to you, fine by me. But for me, it also doesn’t fit in proportion to the rest. You are building 180 sqm here (I didn’t check exactly) with 59 sqm "all-room" and the living room effectively gets about 12 sqm of that. That would be too little for me.
You have somewhat masked it now with a plant and the armchair in the corner. But I still believe you have empty unused space, which I see differently than .
I had already illustrated this graphically.
Another point, the panoramic fireplace. I’m out price-wise, but with fireplace and installation and spark guard plate (or whatever it’s called) and all, that thing probably costs you 20k, right? That’s why it gets a supposedly "prominent" position. Sure, it’s a panoramic fireplace, nevertheless the main line of sight is "in front" of the fireplace. But there’s nothing there. Only around 4 and 8 o’clock you have the lines of sight to the dining table or armchair in the corner. Where I would have expected one to enjoy the fireplace most, on the sofa, I’m already at 10 o’clock.
That means for me the space between 4 o’clock and 8 o’clock would be the "best". That’s probably 10-15 sqm. But somehow there is nothing.
But maybe I know too little about your usage behavior and you leave that space so the parents can lounge naked on a big bearskin in front of the fireplace when the kids have flown the nest.
As I said, if you feel comfortable with it, that’s great, then do it that way. I just don’t like the proportions in the all-room especially in the living room.
