You have given a nice task to an architect. The architect solves many places with "more" space. That is absolutely legitimate. Therefore, the +1 floor will also work. In the 0 floor, despite the available space, I see a few potential weaknesses in the design. The architectural style is a matter of taste; what the pictures show is representative and mixes modern and traditional elements. I cannot yet recognize the narrative arc based on the drawings, but that could be on me. 1. The entrance area is nice and large, which is initially very pleasant. If you are also among the families who leave or even pile up jackets, shoes, and other stuff at the entrance, the question arises as to "where," because very little is provided for that. 2. The living area is comparatively small. The furnishing by the architect does not take into account all the people living in the house. Taking the corner from the terrace and assigning it to the living room would be one way to solve this. 3. Using a terrace as an extended living space corresponds to a lifestyle that we also like to live. That the swimming pool is immediately adjacent has a hotel quality. To what extent you really want it all year round, I cannot judge. If I see it correctly, you could design the property so that the swimming and outdoor sauna area is not on the same level as the 0 floor. This gives you proximity to the terrace but takes the whole thing out of sight during the dark season. By the way, you could possibly build a "convertible roof" over it quite inconspicuously to be able to swim in winter as well. And a few small things: The storage room is large enough to get its own exterior door. Walking paths would be optimized immediately. The side door at the garage set a little further toward the bicycles (the space is not large if each person has at least one) avoids discomfort at the car, especially if the less frequently used favorite vehicles park in a not directly accessible position. Based on the overall proportions of the house, the staircase is too small for me. Not a functional, but an aesthetic question. Also an aesthetic question: The positioning of the office—looks somehow squeezed in. A connection from the pool to the pool technology is very sensible. Think of a cellar door and the storage of all the pool furniture if they should not stay outside in the cold season. Here too, the terracing of the pool toward the -1 level can pay off. If you raise the terrain so high, you can create additional parking space instead of soil and possibly separate the "nice cars" from everyday life. I cannot say anything about the approval feasibility.
