Apartment for parents: 210 m² single-family house and 80 m² apartment

Honestly. Find a house for your family. Whether 3 or 4 children should be clear by then. If child no. 4 is only very, very uncertain, take a room as an office/guest room and that’s fine. It can be converted into a children's room if necessary and that’s it. You have to limit yourselves so that you can even reach the price range you imagine.

Then you have to consider whether a shared utility room would make sense. That means putting 2 washing machines and a dryer in there, as well as the heating and ventilation (if you want). This already saves you a few walls. Also with the thought that the future tenants of your parents might put their stuff in there as well. From my point of view, that’s not a problem. It’s like that in every student dormitory.

Then grant the granny flat in the living room at least 10 sqm more. Once a walker is needed, moving around in the living room is hardly possible. Besides, it’s hard to make such a tiny living room appealing to a future tenant.

Forget the extra access to the garage. The gate and the entrance to the house are perfectly sufficient. The lost bathroom behind the garage is also useless. If you want a washing facility accessible from the garden, put a washbasin there. That’s completely enough. For peeing, you go as usual to the guest bathroom or upstairs. You don’t have to overdo it with special treatment.

Symmetry from the outside is absolutely overrated! We have zero symmetry on the house, but it still looks harmonious (in my opinion). Then take a look at some floor plans on the internet; there are many great ones that perfectly meet your needs with slight adjustments.

Unfortunately, many users here confuse the Nachmal-Planer with a trained architect

Of course. You definitely shouldn't take the previous drafts to the Nachmal-Planer, as he would still use them as a basis.

Then just look up some floor plans on the internet,

I'm afraid there was no lack of that.

Symmetry from the outside is absolutely overrated! We have zero symmetry on the house, but it still looks harmonious (in my opinion).

Apparently, besides people with color vision deficiency, there are also people who hardly perceive proportions. If you still want to try aesthetics then, you resort to symmetry. Simply hoping that something balanced will surely come out of it. Those who have this deficiency can't fit their Golf into a parking space less than 8 m long. That then also makes it uncertain whether 5.5 m in front of the garage is enough.

Symmetry or not, it can also be nice.

But some self-reflection is in order here. What you can't do, you should leave to a professional.

However, I see the dilemma: no matter how great and award-winning an architect delivers his services here - [schustrik] will make it worse by trying to improve it, because something doesn't seem right to him or a contingency has not been considered.

So, another 4 months have passed

I would like to go through the room layout with you.

Please do not comment on where the south side is and that the garage is located there. There is still a southeast terrace that can be extended further to the south.

Could you simply evaluate the room layout and share some thoughts with me about it?
Distances, door swings, room division, room arrangement, etc.

Thank you

Still no architect?

Now no sauna anymore either...

Stairs... well, generous is something else.

Wardrobe for at least 5 people in the larger part I don’t see anywhere.

Wardrobe in the granny flat... well. Dining table a sad little cat table and there is no exit to a terrace from the living areas of the granny flat either.

Technology somewhere far in the south and otherwise nothing planned for the whole complex anymore. What about electrical distribution in the granny flat? And the heating shares a room with a WC... what is that for?

Side room garage... do you need a door directly into the house and another one outside in front of the entrance door?

-------------------------
I would still prefer my version... the middle garage section can easily be extended by another 130 cm (then from my currently planned total width of 23.6 m it becomes 24.9 m.)
But then there is also a sauna, there are 3 equally large children's rooms, there is a sauna with garden access on the ground floor, there is a bedroom upstairs with a dressing room.

And the granny flat is really properly separated (and thus also rentable separately) and there is a really assigned guest room, entrance area with proper storage space, terrace access.

------------
Your wings at the bottom and top of the plan don’t have a uniform line left and right either... I would also be interested in the roof planning.

As a reminder:

Could you just evaluate the room layout and share some thoughts with me?

Don’t be mad at me, but the first thought that came to my mind was: “find someone who knows architecture” and “I wouldn’t want to live in it or invest a cent.” That sounds harsh, I know, but you asked for thoughts. To keep it brief: The kitchen at the top of the plan. 181.5 cm wide. Minus 3.5 cm plaster, 65-70 cm kitchen cabinet/countertop makes about 110 cm, which means in an L-shape not even two 60 cm units on the short leg. It would be more of a kitchenette than a kitchen. Too small for my taste. I don’t get the connecting room either. Somehow overall it feels inconsistent, many strange paths, no rooms that invite you to linger. Overall it just feels cramped, cramped, and cramped. That’s my first impression. Sorry for the blunt words. ’s draft I find FAR better executed, only in the kitchen at the top of the plan I would do without the cooking island, even though I like cooking islands very much. Only in this case there would be too little living room left, and the dining table would be too close to the sofa.
