Construction according to the land register on "uncultivated land"

Hello everyone,

We would like to soon purchase a plot of land in a residential development area which is still being fully developed by the seller. In this context, I noticed the following:

The parcel on which our plot is located is designated with the letter U, meaning uncultivated land, in the land register. All surrounding plots are marked with an A, G, or Grundriss for arable, garden, or green land. Does this result in any kind of restrictions regarding buildability? Visually, when inspecting the planned plot, I do not see any differences compared to the surrounding areas.

I found this in the wiki: The “Unland” is a subcategory of “areas of other use” in the land use directory. According to the land use key, it is represented as follows:

[*
900 areas of other use [LIST] [*]950 Unland [LIST] [*]951 rocks, stone walls [*]952 dune [*]953 decommissioned mining land [*]959 Unland, not further subdivided

[/LIST] Furthermore, the term Unland is defined in the German cadastre as land use group 37000 when recording the actual use of a parcel. According to this, Unland is an area without significant vegetation due to special soil conditions, such as rock, stones, gravel, rubble, sand, snow, ice, or firn. I would have a soil survey done or do one myself before buying. That way you are on the safe side.

Hello,

thank you for the reply. In the meantime, I have submitted an application for review to the Saxon contaminated sites register, which revealed that there are no contaminated sites or suspected contaminated sites on the property. In addition, I am receiving from the seller the results of the soil survey, which he must carry out due to the road construction. So I think I am on the safe side. Since this is a region near where gravel was previously extracted (in the immediate vicinity of a gravel lake), I assume that there will be a relatively thick gravel layer covered by a rather shallow layer of topsoil, which was probably not as pronounced about 50 years ago when the base areas were registered.

What do you think, should I consider anything else or are the points mentioned sufficient?

With the soil survey, you are usually on the safe side. There is then, at least in our case, a foundation recommendation included. The most important thing is that the soil is load-bearing. I would possibly ask an excavation contractor how it can then be compacted. Maybe they can already give you a rough price for the earthworks.

I would assume that the basic soil survey does not refer to the property itself, but to the entire area, as seen in road construction. You can draw conclusions, but this BGG does not replace an individual BGG with a foundation recommendation for the property itself.

What ypg wrote is of course correct. The soil survey should already include 2 investigation points on the property. Ideally, these are the diagonally opposite corners of the future house.
