My house was also on a fairly steep slope (as a layman, it didn’t seem that bad to me). I would also look for a clever architect who builds the building WITH the slope. At the time, we had built a relatively normal house with the eaves facing the street, the neighbors as well. This way, you could drive directly into our integrated garage at the bottom and still had 2 rooms at the front (north side) that could be used (office, guest or bedrooms…). If, as in the picture, even the gable is supposed to face the street, this will in my opinion be an optically tall tower in the conventional way, which I wouldn’t (anymore) like. I therefore don’t believe that a standardized house type is the suitable idea for that. In the end, with us (and your picture shows something similar), it was a huge block and I had a long staircase to the side entrance, embankments had to be supported each time. (Costs) That can be done better and more nicely but probably not off the shelf. The "off the shelf" option sounds initially tempting price-wise but the additional costs associated with this sloping plot will be considerable and in the end, you will have "only" a standardized house incorrectly adapted instead of a deliberately integrated, modern designed residential building on the plot, possibly at similar costs. Take a look in your region for relatively newly built houses, maybe you’ll find something where it’s worth asking the owner about the architect, company etc. We soon outsourced the garage to generate usable space; we had pushed the house 5 meters into the slope and in front there were parking spaces, we never had a garage but plenty of earth and concrete work. You now have the building plot and if you want to stick with it, you should really start searching more in the region with similar terrain than in glossy brochures.
