Read and understand the construction description and performance description correctly!

Hello everyone, we have now bought our plot of land and are about to sign with the developer! Unfortunately, some construction and service descriptions are quite vague and as a layperson, it is not entirely clear to me which services are included and which entail additional costs. Does anyone have any tips on what we should watch out for, which services definitely need to be included, and where hidden costs might lurk? Thanks in advance!

Hello,

my tip: when building with a [Bauträger], involve an external expert as early as possible. Preferably before signing. This person can review both the scope of services and the planning and point out any possible weaknesses.

Regards
