OKAL House Construction - Accessibility of the Construction Site

/ T_im_Norden: Thank you very much for your assessments. I think I will consult a lawyer after all. Merci again.

unfortunately, we were taught better.

What does that mean? What happened in 2020?

According to Okal Haus, they cannot submit a building application as long as the plot is not developed. After consulting with the building authority, this statement would be nonsense, since the plot is developed as soon as a building application is submitted.

Could it be that there is a misunderstanding here? It is about a new development area. It can take up to 2-3 years until everything is developed. Meaning: construction roads, sewer, electricity, etc. will then be accessible for each plot. Could it be that the new development area is not that far along yet? You are pushing, and the house building company is also waiting in the distance until something can be done. The development is often only done when 2/3 of the plots are sold... Then there is, of course, the inner development, meaning from the street to the house... you apply for that after the building permit has been granted. My question: how far along is the new development area? What does it look like? Are some people already building? Are there streets? Is the development completed or not?

The plot is currently not developed, as it is a new development area. An application for development has already been submitted by the plot seller, but it was rejected by the building authority with the reasoning that a building application must be submitted before the development can be carried out.
Okal Haus, however, refuses to submit a building application and demands that the plot must be developed before the building application is submitted.

What we cannot do for you here is: look into your contract to see what was agreed there. For example, who submits the building application and when (i.e. under which conditions). So you have to read (yourself) what you signed.
Developing individual plots would be absolutely unusual; a development plan area usually does not have more than two construction phases, even if it has, for example, four types of building plots. However, many municipalities "collect" a certain quota of plot owners willing to build before they initiate development. Nothing happens quickly here; planning is done in fiscal years. Is your plot located in the "second row," so that accessibility might need clarification? – The mayor of Schilda (where built) even came up with the brilliant idea of surface-mounted development; such a mischievous trick has to occur to one first, although the shame threshold regarding this has shifted in recent years. Discuss the problem with a specialist lawyer (not a "general practitioner" or divorce lawyer!).

Also e.g. who submits the building application

The building application is always submitted by the builder. It is prepared by the architect. Then you sign it and submit it to your building authority.

So here clearly is no fault of Okal Haus, if the plot is not even developed yet.

We bought our plot from the municipality and it was clearly defined in the construction contract that the construction completion only starts from the moment the plot is developed and it is possible to submit a building application.

You were probably misled here into thinking that it is possible to submit a building application beforehand.

You were probably deceived here into thinking that it is possible to submit a building application beforehand.

We don't even know how the new development area is handled. I guess if anything, it’s not deception, but ignorance and talking past each other.
Companies simply don’t say much as long as there is nothing to talk about yet.
should answer the questions first.
