1. Draft floor plan single-family house 150 sqm

The pantry will not have a significant temperature difference from the kitchen and will no longer fulfill Grandma's intention. So it remains only an expensive cabinet with wall and door. This can be done better with kitchen furniture.

I always find sliding doors bad unless they are meant as decorative doors. In the case of children, it becomes a cheerful racket. Crash - sliding door open - sliding door close - bang. That's the end of sleeping in - which might be the case anyway with children. Either way - frequently used doors as sliding doors are just annoying. They always stay open. Then I might as well leave them out or rather use normal doors.

What puts me off a bit is the long corridor in the entrance area. The architect has already tried to bring in light from all sides - good. But will that be enough?

I don't know why you consider the pantry pointless – even though I am aware that it has become unpopular, probably due to a lack of experienced grandmothers. But even in such details, an experienced planner shows. No, definitely do not omit it.

With the dressing room, it is a matter of behavior: if it is actually used for dressing, the objection seems understandable to me; seen as a walk-in closet, this is significantly relativized. My sleep is not disturbed by sliding door wardrobes.

I have to disagree with you twice:
Pantry: precisely according to your argument, the pantry should be integrated into a design. But here it is not – it is additionally placed into a room, which in my opinion visually ruins quite a bit with its slanted wall. But even a rectangular room takes away usable space. The tall cabinets are therefore in a worse position.

A isolated dressing room disturbs the sleeping person because the other has to walk through the bedroom. Possibly even with light.
The storage room, on the other hand, has an ideal position for me.

In short, regards

I also think the floor plan itself is quite good. I wouldn’t have much to criticize about it. However, I would also remove the pantry. I don’t like the slanted wall there; I think it ruins the nice, straight lines that run throughout the entire floor plan. But that’s probably a matter of taste. However, I would consider that you would probably have more storage space if, instead of the pantry, you placed tall kitchen cabinets (like a pantry cabinet, for example) in that spot. In my opinion, that would also make the kitchen appear more spacious. With the pantry, it feels more cramped.

Can you roughly say how much distance there is in the living room from the sofa to the TV wall? Our floor plan is quite similar in style (although we have a square city villa), also with kitchen-dining-living around the corner in an L-shape, stairs placed in the same spot, etc... with us, the distance from the sofa wall to the TV wall will be just 4.01 m. That is definitely anything but generous but should be enough for a cozy living room (we found this measurement very comfortable in show homes). Because of the L-shaped open area, it also doesn’t seem too small. But: 4 m was the absolute minimum for us! We made sure during planning that we would have at least 4 m. I can hardly estimate that for you, but I’d roughly guess it’s about 3.80 - 3.90 m? Consider whether that is enough for you. If yes, then all is good . I just wanted to mention it.

One of the most difficult things I find is the overall positioning of the house; unfortunately, the building envelope is not optimal. The access road runs on the south side. And to use the plot optimally (building envelope), you would actually have to place the house up against the northern building boundary, but then it wouldn’t be parallel to the road.

We faced a similar question. Our plot is slightly trapezoidal. Our plot is the only one in the row that isn’t aligned completely rectangular to the road. The northern boundary of our plot runs a bit diagonally; all other sides are parallel to the neighboring plots and the road. But we wanted to place the garage on the north boundary of the plot. So we had two options: Align garage and house parallel to the road, which would mean there would be a small, diagonally tapering area left between the garage and the property boundary (which would probably end up as a dirty corner, unkempt, hard to mow the lawn there, etc...). Or place the garage on the northern boundary and therefore not align the house and garage parallel to the road. We chose the latter and so we will not set our house parallel to the road. All other houses in the row will be parallel to the road, though. And you know what? It doesn’t bother us . On the contrary, I actually like it. Because this way, at the rear of the house, we have a bit more distance to the neighbor than if it were parallel (quite tight development). Also, the ugly dirty corner that would have formed between the northern boundary and the garage is avoided. Think carefully about what is right for YOU. Whether the house ultimately stands parallel to the road or not is actually not important if it fits better otherwise (unless it is prescribed in the development plan). At first, the idea that our house would be the only one in the row not aligned parallel to the road felt strange to me. But the more I thought about it, the more I liked the idea. So consider it carefully.

Pantry)
I put the misconception that a pantry is just a built-in cupboard into the box of "lost cultural knowledge" - nowadays, more and more people grow up relying on grandparents rather than as orphans. The food doesn't care whether people believe this or not: it simply lasts longer there. This has to do with the greatly underestimated effect of this masonry partition on maintaining a constant climate throughout the day, supported by a continuous ventilation of the pantry that does not disturb the kitchen. The heat transfer alone from cooking steam waste heat through 13 mm chipboard or through 115 mm stone is a difference that the food notices. However, the pantry is ideally located to the north, preferably where the back half of the wardrobe is planned. It is meant for supplies, not for immediate cooking ingredients, so the slightly longer distance is acceptable; a northern location simply cools better.

Sliding door)
What I said about sliding doors referred to wardrobes, not room doors. And not without reason did I differentiate between a dressing room in the literal sense, where the beloved one comes back after morning toilet and then goes through each of the “nothing to wear” complaints every seven meters until the old man is awake; and a walk-in closet in the sense of a simple clothes storage without a half-hour fashion show.

TV wall distance)
In my opinion, this is a less "dramatic" issue nowadays with flat screens than it was with tube TVs. I know plenty of happy healthy people who get along fine with 3m wall distance. For (high-end) audio, room geometry is more demanding than for video.

The pantry in this spot is actually not an advantage. It takes up space instead of creating any. I would consider moving the entire kitchen towards the dining area and then placing a straight wall as the pantry at the back. In my opinion, the storage areas are much too small anyway, while the dining area is very generous.
