Two-story single-family house without a basement with an outbuilding and driveway to the south

The purpose can be questioned. A fireplace produces radiant heat, which feels completely different from the warming of the air by the floor surface. In this and in the coziness, I see a purpose. I would rather "sacrifice" the TV than the fireplace. Everyone is just different.

Basically, it can be a purchased/built garden shed. I once had one (plug-in system with numbered woods), even bought used, and placed it on a base plate. Then I added a storage room for garden tools on the back, all done with simple means but functional. In Scandinavia, simplicity is more the standard, while here it is sometimes done more expensively. Our former sauna in the basement was also comfortable and nice, but then you should have the appropriate room around it because you (I) don’t want to see a workbench or any shelves etc. when coming out of the sauna, but rather a pleasant ambiance. Nature offers that by itself; shivering is a different matter. Heating it up is not the problem and can’t be done differently than inside the house. However, I would rather have it close to the house because you don’t want to walk through half the settlement in your birthday suit or be seen by residents, besides possibly walking through wet grass or rain. Snow would at least still be romantic. Our plan in the current house was actually similar, to integrate the sauna attached to the carport. But for various reasons it didn’t end up being a sauna, but rather a spacious storage room and, instead, a decadent whirlpool in the garden. Electrically that’s no problem, it only requires the appropriate power cable at the location of the action. Today I might do it differently again but for understanding, here are 2 pictures. It was for a holiday apartment and should be implemented with inexpensive (roof battens) but still decent-looking means.

I had overlooked that and thought the entire structure was to be built as a carport. Maybe this project will be clarified by the construction prices or do you absolutely need an enclosed, masonry room for it? I don’t know if this can be settled solely with the position of the sun, but for me the usefulness of a garage would be too dominant regarding the impact on my residential building.

I don’t like this plan with the stairs there/access hallway/living room/fireplace, at least not like that but that’s just my personal opinion.

We originally also definitely wanted a straight staircase... for whatever reason. In the end we took the one whose shape fits our rooms and it became a different but particularly beautiful piece. The straight staircase simply brings complications if you set it as fixed. I believe that the above-mentioned less beautiful or limited possible solution in the open space arises from that. Just because you now have a narrow staircase doesn’t mean it has to stay that way or be avoided through a certain shape; our staircase is definitely not narrow but also not straight.

I have also thought about the staircase. If you don’t prioritize maximum soundproofing, the straight staircase can be built as a walk-in closet unit and easily shifted towards the "north." The study room will be enlarged, upstairs the children's rooms will benefit, while the other rooms become a bit narrower. Instead of the narrow corridor, you simply walk past the open kitchen. The integration of the two traffic flows "hallway" and "passage from kitchen to dining room" is capable of creating space. Just a fundamental idea. The straight staircase is nice after all. We simply have it against the wall without a hallway. That way it takes up minimal space - but we have already moved the children out.
