Procedure for land without a development plan

well, I see 3-4 free plots. Based on the description, I couldn't narrow it down any further

PS: The swimming pond of the villa is pretty awesome.

I have to admit, I could immediately think of 3-4 plots that fit your description

However, I don’t understand the problem? What exactly do you want to know from the building authority? You just want to sell the property, right? Just ask if the plot is designated as building land, and the rest is then the buyer’s problem.

Exactly, and that’s where opinions differ. We have already commissioned two appraisers for an estimate, also regarding inheritance tax, because we didn’t trust the first appraisal. One says it is building land, the other says it is garden land. My concern is about the process, how to sell best. Should one submit a preliminary building inquiry oneself, or leave it to the potential buyer? What format must/should the preliminary building inquiry have? Do you need an architect for it, or is a phone call enough?

As already mentioned, we have had quite a bit of trouble with the building authority, because for another property before the sale they wanted some proof that nothing has changed regarding the volume or something similar since construction. Something like that, I haven’t dealt with it in detail. As it turned out through an architect after more than half a year of research, the employee had given incorrect information and demanded some details that are not relevant at all in a sale.

So I wanted to avoid receiving another false statement because time is a bit tight as well.

Then go to the building authority and have them give you in writing whether it is building land, land expected to be built on, or garden land. They will have that documented somewhere.

... I wanted to avoid receiving another false statement now, as time is also a bit pressing.

Well, apples and oranges. Just because of one bad experience you can't now avoid the building authority, which is your contact point. They still have more solid knowledge than we do.

If you once had trouble with a police officer, you would still report a break-in at your place. That's just how it is.

Nowhere is it written that I want to avoid the building authority. I was only concerned with the form of the request, or rather what should be taken into account.

Should one submit a preliminary building inquiry oneself, or leave this to the potential buyer?

It depends on how much you can or want to take care of it. If you want to invest time and money, you submit the preliminary building inquiry yourself. In NRW, you do not need an architect for a purely planning law-related inquiry. You search online for the appropriate form, fill it out, draw a building adapted to the surrounding development on a current scaled extract (1:500) from the land register, and ask whether the depicted development is legally permissible according to planning law. If the preliminary inquiry is approved, the land is considered building land. What is then specifically permitted—such as roof shape, whether the required distances are met, how many floors, dormers, knee walls, building height—can then be clarified by the person who intends to build there. If you have neither the time nor the desire to deal with the authority, hire a real estate agent to handle the sale.
