ᐅ Semi-detached house without a basement next to a semi-detached house with a basement

Hello everyone,
my husband and I were unexpectedly offered a plot for a semi-detached house under the local resident scheme in the Munich outskirts. The other half of this semi-detached house was already allocated some time ago; we have even met our potential neighbors: their building permit/planning permission has already been approved, and they are just waiting to start construction.
In our case, we want to avoid having a basement not only for financial reasons, while they will definitely build one. In addition, they are building with solid construction, whereas we plan to have a turnkey prefabricated wooden house built.
I have already tried to gather information, but I keep encountering contradictory statements. Some say this is not a problem as long as the basement is built first and supports are installed in the ground on our side; others say it is almost impossible, dangerous, and so on.
Could you provide an assessment? Do you perhaps have experience with a similar situation?
Thank you very much in advance for your help!
Becca

Hm, thanks for the link, but... On these 300 pages, where exactly would I find the information relevant to us? Anyway, thanks anyway.

The relevant information is that a plan should exist for both houses. Usually, it is not a major issue if you build next to an existing basement without a basement yourself. The opposite would be worse, as this could undermine the foundation. Ideally, both halves would be planned together and have the same project manager (this does not require both to use the same construction method). In reality, this is nearly only the case with developer projects.

Many thanks for the clear statement; that really eases some of my concerns!
We are indeed still quite inexperienced when it comes to the whole house-building process (the plot was awarded to us quite unexpectedly – it seems many people dropped out due to the currently high interest rates), and I would like to clarify in advance whether we might be facing major problems. But the signs seem to be looking quite good.
By "one plan for both houses," do you mean an approved building plan / planning permission that the local authority has granted for each?

A joint plan means an architect who prepares a detailed working plan for both. This plan is significantly more detailed than the building permit planning. Details will certainly be explained by @11ant.
