Single-family house floor plan - Feedback wanted

Changing walls and separating floors - that is very unlikely! Think carefully whether you want to build your house on compromises because of that. A 3m living room and the long dark hallway upstairs would be a deal breaker for me.

If the living room is in the basement (???), then best to show it. Ceiling heights there? I don't see any slope in the elevations. What exactly is supposed to be for a living room?

We also build "small" or totally sufficient for us. We have only 2.75 sqm more floor space than you, also with a basement. So I can tell you, you can also put something nice together with 139-131 sqm of living space, but not if you plan like that. An external staircase is a no-go at that size.

Are you building with a general contractor who doesn’t pay attention to the proper terrain characteristics of your plot in connection with the house? What cost estimate have you received? Do you know what the L-beams will cost? How high are you allowed to build up according to the development plan? These are the kinds of questions where the general contractor will leave you hanging....

And one more tip, take a tape measure and visualize the dimensions of the living room (especially the width of 3 m), bathroom, kitchen, etc. On a 1:100 floor plan many things look great, which don’t make sense in reality.

I don't like the design. Strange corners in the walls of the dining area. But complete tightness at the sofa. Considering that our sofa has a basic depth of 140 cm... hehe... you sit nose to the TV, while on the left there is unnecessary space at the dining area. Additional view into the pantry... no ergonomic workspace in the kitchen... for me, the spatial proportions don't fit at all, measurements and relations are not considered. You can also see this quite well in the Pax hallway planning at the door side: no wardrobe fits there. And what is that in the kitchen? I would rather not want to use the staircase in the entrance area. If the house is divided into 2 residential units, then upstairs there is an oversized bathroom but a tiny multipurpose room without a balcony, downstairs an oversized kitchen that can possibly be closed off. Only from the outside is the house my type.

I have already manually added the fixed changes to the plan

It seems to me that originally the corridor wall extended up to the height of the chimney (?) What kind of monstrosity is that actually, which is marked as chimney stack intake in the kitchen?

we are therefore planning the non-load-bearing walls in drywall.

Well, then take a closer look at how few those could be. Actually only the one between the dressing room and the bedroom. Apart from that, nowadays you mostly build with underfloor heating, which makes subsequent redivision somewhat more complicated. Houses are immovable, but tradable. A house "until death do us part" will soon rather be the exception model.

I don't see any slope in the views.

No, but there and in the floor plan a slope as a kind of large light well. The slope is already excavated in the drawings, and only visible at the "stairs" in the terrain (north of the garage).

The thing in the kitchen will be an oven. The piece is located by the chimney.

I would swap the living room and kitchen on the ground floor. Omit the storage room, or integrate it with the WC.
