House Design
Who designed it: put together myself
What do you like most? Why?
- Direct access from the bedroom through the dressing room to the bathroom
- Cloakroom niche keeps dirty shoes outside the main passage area
- Floor-to-ceiling windows for lots of light
- Straight staircase, looks modern, easier to walk on than a spiral one and better for accessibility later (stairlift)
- Very spacious living/dining/kitchen area (though perhaps too large?)
- Pantry with everything easily accessible on open shelves
What do you dislike? Why?
- Huge waste of space in the hallways

Why did the design turn out this way?
I saw a similar layout in a townhouse that I really liked at first glance. We want a generous living feel with large window areas.
Since we are planning without a basement, an extra room upstairs was created for storage, guest room, and workshop space.
Important: the bathroom layout is not really planned yet. I have inserted my first idea there but I know it is still far from a “good idea.” For now, the focus is on the basic room layout. The windows are currently more of an idea than fully thought through.

What is the most important / fundamental question about the floor plan summarized in 130 characters?
- Do you see a way to reduce hallway space despite having a straight staircase?
- What is your overall impression of the design?

The base model is the Solitäre 165, but on the website, you can only find various designs based on it (including extensions).

It's a pity, because this makes it difficult to get an impression of how the original model would look as a building form. All the images available make me wonder whether one has to be a bit of a trickster to speculate about any connection between Schwabenhaus and Bien-Zenker. After all, they are associated with Living Haus, which is effectively a subsidiary.
In any case, you have clearly "freed" your version quite extensively from this base model — right down to the straight staircase now. What seems most important to me is that it looks functional. Whether I am convinced by the way it fits into the terrain, I’m not quite sure yet. Your descriptions don’t fully convince me; I would prefer to see a site plan with elevation points.

The site planning is still quite a challenge, and I don’t want to sugarcoat that. However, the property extends along the slope for a considerable length (a good 32m (105 feet)). So, we assume that we can build the carport, house, and terrace all at the same level without issues. How to proceed with the lower part, where the slope continues to descend in the garden, is still unclear. The local council itself isn’t quite sure yet either and is currently under pressure from many builders who need to find practical solutions for managing the elevation differences.

Do you see the problem mainly in terms of costs or the overall feasibility? I’m already worried that we might significantly underestimate the financial aspect, but I’m not sure how else to handle it...

I hope for my own peace of mind that you’re not getting the idea that a straight, single-flight staircase would make anything easier. For floor plans with edges shorter than 12m (39 feet), you wouldn’t even need to look—single-flight straight staircases are, like symmetry dogma, though at least these two notions only weakly overlap, a prime example of a space hog.

I’m currently following your advice and reading the other topic, and I came across this post from you. Do you also find the staircase in my floor plan that bad?

No. The fact that it still works in your case is because, as I already mentioned, you are not trying to squeeze “thirteen wishes into twelve square meters.” Probably due to the interaction with the high knee wall, things are working out this time that normally wouldn’t fit. But this is something known from nature as well: contrary to theory, bumblebees can actually fly. So your staircase is, in a way, an exception to the rule.

Once again on the subject of the slope: I have attached a cross-section of the plot. What is your view on this? What do you think about it?

Section plan: garage, multi-story building basement/ground floor/upper floor, base and scope, axis 10.

That looks like about a 1.85 m (6 feet) height difference around the house area. Based on the now well-known and assumed opinion of 11ant, this is a clear indication of a basement. However, without placing the specific house within the property, it is not possible to determine what kind of terrain shaping this would imply at which location.
