Should Baufritz also be the builder, or were they just the source of inspiration? - I find the dimensions surprising, as they suggest a building that is not made of masonry, but on the other hand, the window dimensions are taken from structural (shell) measurements typical for masonry construction. Have we ever discussed the topography? - at least I don’t recall that, and I couldn’t find a site plan with elevation details. Does the "difference" here refer to a slope or an incline, and is the hillside really that even (and only in one dimension)?

I agree that the T-shaped bathroom is a design mistake and don’t expect it to be changed during the first bathroom renovation. In fact, I wouldn’t build it like that anymore today. However, you can no longer rely on trends. Twenty years ago, very high heels became fashionable—a trend I used to think of as a reliable flash in the pan that disappeared after just one or two seasons, and now it’s gradually fading again. White cars were also a reliable trend during my childhood and youth, only to become hard to sell in the used car market three years later—but currently, white cars are back as a lasting trend. On the other hand, the deep red bay windows of the first series of alternative villas have long been out of style, smoky eye makeup is declining as well (but more slowly), and corner windows represent a weaker but much longer-lasting trend. The open-plan kitchen commonly seen in TV cooking shows for ordering pizza does not seem to be fading even slightly. I recently heard from Moorhuhn that it is preparing for a comeback.

In short (or rather mediocre): trends today are no longer reliable and, if strong, tend to be short-lived. So, in my opinion, you cannot count on the T-shaped bathroom becoming a negative factor when reselling in ten years (unlike sanitary fixtures in moss green or Bahama beige back then). Still, I believe that anyone brave enough to ignore this trend today would not be penalized when selling later.

Conclusion: if you personally really love it, then go for it. Otherwise, it’s probably better to stick to a more “classic” design.

No. They were only for inspiration. It turned out to be too expensive for us at 3,000 EUR/m² (about $3,200 per sq ft). We are building with a local carpentry company that specialized in single-family homes years ago.

Unfortunately, there is not yet a survey, as the development plan is still in progress. According to assessments by several general contractors who have also visited the site, a single-family home on a slab foundation is feasible. A slope or retaining wall along the west-north boundary of the plot will probably still be necessary.

The plot has a slope of about 2.5m (8 feet), which flattens significantly toward the street. The slope of the excavation pit itself is only about 1 to 1.5m (3 to 5 feet). The plot is planned to be shaped into a plateau.

Your answer about the height issue doesn't really clarify things for me.

Which federal state?
A garage 3m (10 feet) wide built on the boundary line could conflict with the required setback distances of half the building height (1/2 H) in some federal states, especially if the main building is 8 or 9m (26 or 30 feet) tall.
