We want to build the basement into the slope. Only the terrace should partially "float free". The kitchen and dining area should have the best view. With friends in a similar living situation, we regularly sit on the terrace or in the dining room with a view into the distance.
Although we don't live on a slope, we regularly spend holidays in a hillside house and are in the upper apartment there. Now with a child, I find it very impractical that the garden is one floor below. You either have to go up and down all the time or plan accordingly from the start. By the way, the view from the garden is almost the same. If you place a tree right in the view, the extra 2.5 meters in height doesn't really matter. Rather the opposite: you can look past the trunk, the crown is then directly in front of the balcony.
