Hi, sorry, yes I can already see that a few pieces of information are missing. The building will actually have 3 floors. For me, floors were mentally located "starting from the basement" and not including the basement. So the plan is for a basement that is exposed on the south side and partially on the west/east sides, as indicated in the drawn picture. The exposed area will be used as a library/hobby room/guest room. The garden will be leveled at the height of the basement floor slab with a retaining wall towards the southern end (left side in the section). Yes, retaining walls towards the parking spaces are definitely needed. Possibly, these will also be designed as small terraces. That still needs to be planned in more detail with the landscape gardener. So far, we know from the neighbors on the left that they also plan the garden level as we do. The plot on the right still belongs to the city and is still reserved... meaning nothing will probably happen there soon. The valley-side view is great. In front of our property (i.e. on the south side), there is a fairly steep slope. So there is no one to build anything right in front of you and you have a view into the valley and the opposite mountain side. The plot marked on the overview plan as 14.4m wide (light gray lines). The red line in the plan is the building envelope for garages/carports. According to the development plan, these must be located 5m from the street. Accordingly, my first draft has also resulted from this. In the section of the plan, south = bottom. The 4m in front of the house are intended to serve as an entrance area/front garden, where the waste container box, the greened heat pump, and the dog's wash place are to be located.
