ᐅ Living Room Layout Planning Ideas?

Yes, everything can be changed. How would you position them, Schubert? I appreciate any tips.

It’s basically about the size of the living room

In principle, the size of the living room is sufficient. It really depends on the furniture.
A corner sofa + armchair + large wall unit obviously require space. If you really want to use your old furniture, my first consideration would be where I need less room (with the same floor plan size). Then I would think about how to adapt the rooms to my needs. In other words, what does my ideal living room look like, and does the kitchen-dining area have to be arranged exactly like that?
I think an extension is a really bad idea.
You also need to consider that adding 1 meter (3 feet) in length and width will also affect the upper floor and can become quite expensive.

Are you building without a basement? What is the orientation? Where will the garage be located? What should the attic look like?
To really find a solution for the whole house, too much information is missing, including your own ideas and preferences.

Thank you, Tichu, for your assessment. Both options, the extension and the 1-meter (3.3 feet) addition, have been fully calculated with the builder and result in the same cost. Your considerations exactly match our approach. However, apart from the hallway, there is basically no space that can be reduced without affecting the layout of the kitchen/dining area. The house has a basement, and the entire living room side faces south, with the kitchen facing southwest. In the attic, adding 1 meter (3.3 feet) to the front of the master bedroom and one child's bedroom would increase their size, which is acceptable since these rooms are smaller. The garage/carport is located on the north side by the driveway entrance.

Our idea is that the main living area, where most of the daily life happens, simply needs to be a bit larger, whether with existing or new furniture. The extension would make the floor plan a bit more interesting but at the same time would disrupt the appealing symmetry of the house. That is why I wanted to hear other opinions.

The house has a basement, and an additional meter (3.3 feet) down there is probably not necessary in terms of usefulness.

I don't like the overall floor plan either, but that's just my personal opinion. I agree with Tichu78. I’m also not happy with the layout of the living room, dining area, and kitchen, and the hallway is too large for the size of the house.
Like Tichu78, I think the extension is the worst option. If at all, then option 2, but the windows don’t fit there.
Have you tried any other floor plan variations?

It’s great if you can afford it... but you should really ask yourself if it’s absolutely necessary. Imagine there is a better floor plan with fewer square meters (square feet)? Size isn’t always the most important factor.
The hallway also seems too large to me. You could definitely reduce it a bit. With such a large house, there are certainly other floor plans that better match your ideas.
A 10m x 10m (33 feet x 33 feet) house with a basement gives you a lot of freedom... The staircase is key to a good floor plan. Maybe that’s where you should start. Straight stairs or two 1/4-turn stairs with a landing—the quarter-turn staircase is certainly a good option as well.
If you search for “townhouse floor plans” online, you’ll find many alternatives.
I would suggest moving the kitchen, dining, or living area more towards the center of the house to allow for more space across the entire width.
