Opinions on single-family house floor plan

We thought that the 45° corner on the ground floor would loosen things up a bit and then you wouldn't have such a "sharp" edge in the middle of the living/dining room, and it wouldn't be a rigid rectangle? But the argument with the tall cabinet is also appealing... I have to discuss that again with my wife.

If you make the hallway in the upper floor right-angled, the whole wall must be shifted upwards somewhat, and then the children's rooms opposite the bedrooms lose even more floor space, don't they?

We also considered two sinks, but we currently have two in our apartment and noticed that we actually only use one of them.

In the upper floor, you should definitely try out the bed placement, so you don't bump your head.

Bedrooms under a sloped ceiling on the upper floor existed before, exist now, and will continue to exist despite the city villa craze. It works fine with the indicated 2-meter line :) I'm only writing this because I have read it from you several times, even though there was a common 2-meter line on the upper floor.

We also considered two sinks, but we currently have two in our apartment and have paid attention and noticed that we actually only use one of them.

But you want to be four people at some point - and the kids will grow up! Then bathroom use looks quite different again...

Edit: Pantry gone, use the gained space as a wardrobe without walls.
Remove sloped wall in the kitchen, as already says: useful space is lost due to the sloped wall.
Upstairs I would leave the sloped walls... there are already so many that they almost create a straight unit in the hallway ;)

Something like this (is a bit difficult since your floor plan doesn’t have any real measurements):

I’m following floor plan posts purely out of extreme self-interest ;-)

I would have suggested similar improvements as already mentioned here.

It’s very important to me (we currently have this combination), that the pantry and utility/technical room are separate...
The dryer produces so much heat that food doesn’t always like that... (The heating system is currently in the guest bathroom - it’s always very warm there too... I don’t want to have that later in the same area as the “storage room.”

Regarding the topic of 2 sinks: for us it was absolutely unnecessary (kids are now grown and thus we have experience)

Nobody needs that... when the kids are old enough that you might need 2 sinks because everyone wants/has to get ready at the same time in the morning, the kids no longer want to be with someone else in the bathroom at the same time :-) Siblings also eventually want their privacy...

I myself also prefer to be alone in the bathroom, wake up properly first, and can be a morning grouch... what good are several sinks when you’re already grumpy in the morning because no one is fully awake yet and everyone has to/get ready in a tight space...

Our solution for that: second shower/sufficient sink in the guest bathroom - that works better :-) - otherwise a clear schedule has also worked wonders ;-)

Correction:
The technology is in your basement anyway (sorry, I was just thinking about a different floor plan^^) - so there's no danger of the pantry and technology being in the same place...

Personally, I wouldn't do away with the pantry. Even if most of it is probably stored in the basement (drink crates, potatoes, and so on), a pantry would always be planned for us personally, if the floor plan somehow allows it.

Thank you very much for the answers already.

My wife is still not quite convinced about removing the pantry and has proposed the following alternative (see attachment).

In my opinion, the pantry is then so small that it is no longer in a good proportion and you don't really gain much space with it either.
