Convert green space into building land

Hello,

we have the following concern and since this will be our first house construction, we hope for a few helpful answers :)

My wife and I have been looking for a house or land for years and so far we have had rather little luck.
Two years ago, a new development area was established in my parents' village.
The municipality bought a large part of a farmer's property (green space) for this purpose.
When we looked at the new development area a few days ago in search of building gaps, we saw that directly on the street of the new development area, there is a roughly 3500 sqm "building gap" which is a wild meadow.
This gap borders directly on the last new house and, as mentioned, is also located directly on the residential street.

Since I know the owner, I thought I would ask...
Originally, the municipality wanted to buy the entire green space from the farmer.
At that time, he only sold them "15000 sqm" and they could not agree with the municipality about the adjoining green space in which I am interested.
The municipality nevertheless developed the road further because they were sure they would still get the property.
Since he cannot stand the current mayor, who apparently also threatened him with expropriation, he said he will definitely not sell to the municipality.

However, he would sell us a part of the property of about 600 sqm.
Now my question is, since it is a green space, whether and with what effort it is connected to turn it into a building plot?
Can the municipality refuse a land use change out of spite?
What are your experiences? Also regarding a possible time frame.
Thank you very much for your answers and sorry for the long text :)

Development land is not building land Whether you can still build on it during your lifetime is something no one can tell you at the moment. Perhaps the municipality does not want any trouble and will buy the next building area elsewhere. Maybe a new mayor will be elected who buys something from his brother-in-law (of course a nasty stereotype about rural life ;) )

Your question is an evergreen and resurfaces here about once a year, take for example this thread: (or some others with search terms like Grünland, Flächennutzungsplan etc.). Basically, a development plan has a scope of validity, and only there does it apply, - not everywhere where you can see or even spit on the scope of validity. Adjacent areas are generally only tackled when the existing designated building areas are about seventy percent sold out and demand persists - before that, very rarely. The procedures are too complex for a municipality to stockpile building land designations or even development at large scale. Experience shows that areas which have usually been excluded in previous building land designations due to some competition over which stubborn party has more staying power are taken up with particular low priority - rarely before at least one of the disputants has moved to the graveyard.

I also currently have such a case. My property is located directly on the town boundary next to the last house, but it is in an outside area. Three weeks ago, I had a 1.5-hour appointment with the mayor and two employees who informed me about the legal regulations. At present, there is no possibility of an individual permit, only if the entire area is changed in the land use plan as a built-up area. The disadvantage for me is that a new development area is currently being designated in our town and there are also some building gaps. Only when the development area is sold out except for 2-3 building plots do they want to start something new. I was told we can talk again in 5 years. The street runs past my place, water is available, and the sewer would only need to be extended a little. Thus, almost all infrastructure is available! It is also problematic that it is very difficult to designate new areas because the legal rules aim to reduce densification to protect the land resource.

Basically, I can only tell you that if the municipality is not willing to do something there, you won’t build a house there. The only option is if you know someone in the district office, but they also have their regulations.

Based on another thread ( ) here: Alternatively, you create a large pond on the property and water a large houseboat. Or park one to three motorhomes on the property and move them a meter every few weeks.

Currently, there is no possibility for an individual approval, only if the entire area is changed to a built-up area in the land use plan. [...] The only possibility is that you know someone in the district office, but they also have their regulations.

And even if it is the district administrator personally - the land use plan is state development. The district administrator can only intervene as far as he meets the prime minister at the buffet of the Red Cross / VdK / Kolping or similar. A single-family house might create about eight jobs for half a year - but you won’t be feted anywhere as an "investor" for that ;-) Incidentally: whether densification reduces land consumption, I mark with a big question mark. As far as the expansion of the territory is concerned, yes, but the sealing inevitably increases. One might save street space, but that is put back out of the other pocket at the pipehead driveways again. What might bring (a bit of) relief would be a trend towards two-family houses as the most space-efficient building form.
