Hi,
I find Haydee's response and recommendation very good and important.
I get the impression that you - from looking at the floor plans you have presented so far - are not yet sufficiently clear about the basic concept.
I do not want to evaluate them further or say that they are bad, no - they are simply very different.
Before you consider further details, you should have a "concept" in place, because the problem will be that you will get 6 opinions from 5 people here. That will unsettle you even more.
Everyone will have their own opinion about the floor plans.
Building is too individual, and if you have the opportunity to plan individually and the budget is not the all-limiting factor, take your time!
And get professionals on board.
For example, you can also build with the goal of addressing as large a potential buyer target group as possible when selling.
Or very individually....
A concept immediately came to my mind with large glazing to the south - with rooms opening outward - connections between inside and outside.
But my preference does not have to be yours.
In your new draft, the huge cellar is now missing, and from minimal windows to the south, you are now almost at the maximum possible glazing.
These are such stark contrasts that I would like to advise you to fundamentally - as also suggested by Haydee - look at houses and rooms and get a feeling for how spaces work.
A 20-meter-long and 6-meter-wide living-dining-kitchen area - it is personally hard for me to imagine that one (better: that I) can feel comfortable in it. But as I said, everyone is different, and for you, it may be the right thing.
But you need to get a feel for these room dimensions - paper does not adequately convey the spatial feeling.
My well-meant advice: have an architect make the designs, preferably several.
Look at houses, do you find one you like? Which architect built it?
Is there anything interesting at the architecture day?
....
Every architect implements a certain "style," that is our experience. If they can plan freely.
When building, you ideally need as much as possible of all 3 things: money, time, experience/knowledge.
Besides good nerves.
Think about which you have a lot of and which you don’t.
What YOU want to build is crucial.
Cheer up, I know exactly what it’s like to be stuck in such a situation.
Be brave, take a deep breath - clear your mind - carry on.
But no hasty decisions if you are not sure.
Best regards
