I like the architect's version best, but I would swap the kitchen and guest room as you yourself already suggested... especially if you have such a great view of the nature reserve, I would prefer to have that from the kitchen rather than from a guest room that I probably won't use much in the first 20 years while I'm healthy...
I was thinking more of leaving the guest room where it is and arranging kitchen/dining/living room in an L-shape, right? That way the sun would be in the kitchen early and not just the morning twilight, and there would still be light in the living room in the evening.
I think it's good that the utility room is separated from all the other rooms here, but I don't know your upper floor... have you set a budget (that could be the reason why the basement was omitted, otherwise why have a utility room?)
You wrote, as I saw above, that you want to enter the house through the garage, so you would need a mix of the proposals...
Budget was known and still utility room on the ground floor ("I initially put it there" was the statement)
I see a classic turning hammer on the plan... Property therefore, in my opinion, can only be accessed from the northern corner...
If the garage is placed on the north, you of course have a very generous south terrace...
What would be personally important to me is how the whole thing looks from the outside... it is a completely different building volume with the various proposals...
That is just a dead-end street... no place to turn around. I was thinking to place the garage to the right of the house, right up to the boundary. Thus a larger south/west terrace.
The basement will probably be quite generously exposed in the southwest as well. That means the terrace should rather be to the south with a slope or retaining wall. Is a proper basement to be created in the basement? What about the upper floor: knee wall, so a nice pitched roof? Considering the overall size and costs, I see a large ground floor (because of bedroom possibility) and generous living area, a basement with the possibility of heating from an office? And therefore because of costs a rather smaller upper floor. Or could the children's rooms be in the basement with terrace exit to the west, ground floor and no upper floor? [emoji848] The slope is always the problem for a layman to estimate correctly.
We then wanted to use the excavation to build up with retaining walls like these L-blocks. Basement was not planned. Knee wall is no topic, we thought of 2 full floors. Without upper floor, it is like without a basement.
All ground floors always have upper floors and these always have to be considered together. But the upper floors are missing.
Is the land to be built up?
In one example, the house technology is omitted because it is probably in the basement, where the wardrobe can also be created.
There are not so many possibilities with the upper floors, I think. I can still post. Yes, build-up.
Did the architect provide a section with terrain heights or something like that?
No, not yet. We haven’t had our own surveyor on site yet. That is included with developers.
The lower living area should just be open and welcoming.
Thanks for your effort!
