Assessment of our potential property

First of all, I would like to thank everyone for the great participation with many helpful contributions! In this post, I will address the access situation, as it is really not that simple, and in another post, I will ask a few questions.

Realistisch betrachtet sehe ich eine solche Zufahrt von einer Kreisstraße etwas utopisch bzw fahrlässig an. Und bevor man dann es nicht weiß, kann man keine Pläne machen.

In post #3 you see Option A with access via the old town, a turning hammer, and the same exit. In the municipal council discussion, it was proposed that the entrance/exit could be made via a path (between property 7 and 8). Here, the urban planner said that there would be a long-distance water pipeline (?) there and that legally, one is not allowed to build over it. The council’s objection that the turning hammer also covers the long-distance water pipeline by 25m was dismissed with "Yes, but the street would be 35-40m long". Does anyone know the legal situation regarding building over the long-distance water pipeline?

Option B runs along the district road. There is a sharp curve there (not visible in the sketch). This means a turning lane would be required. The district also wants the advance payment for road maintenance for the next 100 years. For these reasons, this option would be significantly more expensive.

The driveway is at the bottom right... you are planning the garage at the top left... also, it is high in the north, low in the south... or did I misunderstand something?

That’s exactly right. Access will only be possible via the cul-de-sac. The path behind our property is an agricultural road.
We would like to place the house as close as possible to the driveway. Reasons for this:
1. No further sqm waste due to the driveway. 2. The view is most attractive and unobstructed there. 3. Our current house has the garden arranged exactly like this, and we find it a pretty good mix of sun/shade for sitting outside.

As for the layout, we thought of:
Basement: garage, utility room, storage room
Ground floor: study, living, dining, kitchen, study
Upper floor: bedroom, bathroom, dressing room, 2 children’s rooms, children’s bathroom

I still don’t see the advantage of not putting the garage in the basement. In our case, it probably doesn’t make sense to build without a basement, and I don’t see the benefit of placing living spaces in the basement and putting the garage beside the house instead. Am I misunderstanding something here?

Another question: do you see any possibility on my green sketch to redesign our driveway somehow? It really annoys me given the sqm prices and follow-up costs. Can’t the urban planner solve this more cleverly somehow? By rounding off the property boundaries or something?

Am I misunderstanding something here?

Yes, a bit I unfortunately don't have time to explain it right now.

In post #3 you can see Option A with access via the old town, a turning area, and the same exit. In the municipal council discussion, it was suggested that the access/exit could be made via a path (between properties 6 and 7). Here the urban planner said that a long-distance water pipeline (?) would be located there and that legally it may not be built over. The municipal council's objection that the turning area also overlays the long-distance water pipeline by 25m was dismissed with "Yes, but the street would be 35-40m long". Does anyone know the legal situation regarding building over the long-distance water pipeline?

Sorry, I just realized that I may have expressed myself unclearly here. The suggestion was to enter the development area from the west via the marked road and exit via another road between properties 6 and 7 (or vice versa). Here the urban planner then raised the argument about the long-distance water pipeline. What is your opinion on this?

Otherwise, I consider the questions premature given the planning status. A sensible house design, including the positioning of the building on the plot, is only possible once the conditions of the development plan, the infrastructure, and the elevation are sufficiently and definitively known. The decision for a plot at this location seems to have been made. Or does the location of the building envelope still influence whether the reservation will be accepted?

You are probably right. All the brainstorming is just that until then. And no, the reservation definitely remains in place since it is "the most beautiful plot," with no cables or anything running through it. The biggest downside is the driveway from the turning circle, for which unfortunately I cannot think of any other suggestion to communicate to the municipality/the urban planner.

How do you see that?

Without the urban design draft, I see nothing at all. I consider it impossible to discuss all the planning considerations here on the marketplace, taking local conditions into account. The proposed alternatives do not change the fact that your property cannot be accessed from the north.

because it is "the most beautiful property"

... unfortunately, I see no room for negotiation for you. You will probably have to swallow this toad. The municipality could have designated your access as a public traffic area (you can still record this during the public display of the development plan). But this not only reduces the profit, it also causes additional costs. Why should anyone harm the community when there are enough developers who will accept the property as it is. From an NRW perspective, you are even lucky. Here, entire dead-end streets are often designated on private building plots and are burdened with pedestrian, driving, and utility rights, i.e., the entire neighborhood drives over your property and when something breaks, the hassle about paying begins.
