ah, now I understand :) thank you very much I would plan the driveway on the first half as steep as possible, taking overhang and wheelbase into account. For people who want to come to us on foot, I can put a staircase where the house connections are, right? The company even told me yesterday that it might be worth considering returning the property :( we didn’t want to hear that at all, but if there’s no other way ...
I already designed a 15% driveway for you with a low SW portion. 15% is little in relation to the property, which has 25%. That is easily manageable on foot. If someone with mobility impairment comes to you, they can just drive up with the car. You have to think with the slope. Some well usable flat areas arise with reasonable planning. The huge garage and hallway under the house do not belong to that. The development plan doesn't make it any easier either.
