Single-family house layout planning - first planning draft

is a very special floor plan with a very spacious hallway and a very spacious kitchen - the question is whether this is in proportion to the house.

4.14m from the sofa to the living wall is definitely sufficient - if it were my floor plan, I would try to make the hallway a bit smaller and possibly choose a different staircase design so that you have more of the living room. You have more than enough space in the hallway - plus a vestibule and a huge wardrobe. So maybe you could create more space there.

I somehow find the pantry awkward, especially the door to the garage? You have to walk through your pantry every time to get into the house and then come out in the kitchen - I find that kind of strange, but of course it's a matter of taste. Especially then the two doors in the pantry... I would also leave out the door to the garage.

Of course, the kitchen is huge, you can definitely make something great out of it. There's even plenty of room for a seating area. If you like a spacious kitchen, go for it.

Regarding the upper floor: currently, you don't have space for a large wardrobe in the bedroom. The shape of the bedroom is naturally not ideal for a normal wardrobe. You would have 3.25m space, but then it gets quite tight near the window, in front of the bed, etc. So I would actually change/adjust something there.

I somehow don’t think it’s so cool when you come in the door and see the shower cabin (probably made of glass) straight ahead. I don't find the bathroom layout optimal, but of course, that's totally a matter of taste. The staircase also takes up a lot of space upstairs.

I also think that the living room suffers in size. Rather swap living room and kitchen, but actually I would redesign the ground floor. And I would also leave out the strange short walls in the upper floor in front of the toilet and in the ground floor by the [windfang].

I would make the laundry chute accessible from the hallway. Back there in the corner, it bothers the toilet user, and the path to it is too long for lazy people, possibly undisciplined children. The huge pantry takes up space. Empty space is created in front of it. The passage from the kitchen to the dining table is too far. It makes sense to plan the living room in the quieter part and align the kitchen with the dining area; therefore, I would swap the living room and kitchen. There is a lot of empty space on the ground floor. The hallway is large, in my opinion far too large... I would place the stairs to the south so that it can capture the southern sun there, which benefits the whole house. The guest toilet in the east, toilet in the south is casting pearls before swine. Definitely furnish once with your own furniture and make the space that is now the kitchen square.

a very special floor plan

Yes, I don't even know what I like better: the porch post right in front of the garage door, or the interior window next to the sofa ;-)

Therefore, I would at least provide a simple shower/WC in the basement because of the sauna, and who knows how the office down there will be used in 10 years.......

Shower and WC in the basement probably require a lifting station. A relatively small one is sufficient for the shower, but it gets more complex for the WC. It should also be maintained regularly. Therefore, we opted out of having a WC next to the sauna and implemented "only" the shower. Depending on the location, the lifting station for heating drainage can also be used for this. By the way, we are glad to have switched from the 1.4 x 2.0 m sauna on the upper floor to the 2 x 2.5 m one in the basement. Even nicer would of course be 2 x 2.5 m on the upper floor, but the floor plan didn’t allow it due to other bathroom requirements ;-) .

However, the shower and toilet in the basement probably need a lifting system. A relatively small one is enough for the shower, but for the toilet it gets more complex. It should also be maintained regularly. That’s why we decided against the toilet next to the sauna and "only" installed the shower. Depending on the location, the lifting system for the heating drainage can also be used for this. By the way, we are glad to have switched from the 1.4 x 2.0m sauna in the upper floor to the 2 x 2.5 in the basement. Of course, 2 x 2.5m upstairs would be even nicer, but the floor plan didn’t allow it due to other wishes in the bathroom ;-) .

True, but depending on the need, it "has to" be with a lifting system. An acquaintance uses it and apparently it works quite well, but I don’t have personal experience with it. I feel similarly about the sauna size. In the living area, it usually turns out relatively small, which is why I prefer it outside and now want to possibly implement it in a new building. A nice basement area is of course also great if available, but in my opinion, the size must be there. My first self-built sauna back then was 3x2 and I kept the fronts in simple glass with a view into a nice room area, which is something special. I just don’t like the sauna in the laundry room or something similar.
