Widen the building plot by 3 meters

Hello everyone,

we are interested in a building plot. It is currently undeveloped and located in the last construction phase of a new development area. The development of the plot will take place next year. At the moment, it is still farmland.

We already like it quite a bit, but ideally, it would be 3 meters wider. Since the neighboring plot (same owner/seller) has not yet been sold, we are considering whether we could extend "our" plot by 3 meters in width. The seller was also not opposed to this, as it would allow them to cater to interested parties looking for a smaller plot. ([Plots of the same size are still available]).

These additional 3 meters will probably be quite expensive, because in addition to the higher purchase price (3m * length * purchase price), higher development fees (due to more sqm), there are also costs for changing the plot sizes.

I am currently trying to estimate how significant the last point is and whether it is worth it for us. I am calculating a four-figure amount. What needs to be done to make this possible? The plots probably need to be newly surveyed. It may be necessary to create a new cadastral parcel, which will then be merged with "our" plot. Is it advantageous that the area is not yet developed and, for example, no boundary stones are set yet?

What steps are necessary to obtain the 3 meters from the neighboring plot, and how expensive will it be approximately? At which office or offices can I get information about this?

Thank you in advance.

As far as I can tell, you estimate the processes completely correctly. The cadastral office is responsible for your application (or that of the current owner of the affected properties). Then you need a surveyor, as the new boundary must be surveyed. The office and the surveyor charge fees, and you are probably correct about the amount.

And of course, all costs related to size also increase with the size of the property.

Has rezoning already taken place, or do the properties still currently have the formats from the time of agricultural land use?

I do not know exactly what "umgelegt" means, but in the plans such as [Bebauungsplan] and [Flächennutzungsplan], the building plots are already marked.

Is it estimated to be more like 1,000 or 3,000 or 5,000 euros or more?

4 digits for 3m more width? A dream...we took 2m more width. It cost us 28,000 EUR. Plus about 1000 EUR for the "bureaucracy".

28,000? But that includes an appropriate purchase price, I hope. How much less would it have cost you if the 2m belonged directly to the property? 1,000 euros for changing the property boundaries. Is that correct?

4 digits for 3m more width?

No, he wrote

... and for that it should be suitable, as you yourself write

About 1000 EUR for the "bureaucracy".

I don't know exactly what "umgelegt" means, but on the plans like the development plan and land use plan the building plots are already marked.

Arable land is long and narrow so that agricultural machines do not have to turn around so often. That is not suitable for building. Therefore, nowadays (for many decades, unlike great-grandfather's times) a land consolidation process is first carried out if a building area is to be created from it. Simply put, all farmers put their plots into one pot and receive more suitably sized pieces of the same size for building in return. Sometimes this is done in sections when that part of the building area is to be "opened". If this consolidation has not yet taken place here (i.e. completed, including surveying) your request causes a little less extra effort.
