modern Bauhaus, lots of glass, 170 sqm ground floor/upper floor, currently in phase 3

here it is partly acted as if the only reason for the house is to really show off to the neighbors :) And not at all because one likes the style. The OP hasn’t responded anymore either.

and for example refer to the thread by @benediktr.

How am I supposed to understand that :-) You definitely can't compare the planning costs with mine...

Did you manage with your initially planned budget for the house construction?

We are still building and had plastering done two weeks ago. According to the current estimate, I will manage. However, it must be said that there is a huge amount of own work and good connections involved. On the other hand, there is a higher standard such as KNX, continuous parquet flooring, high-quality windows, lime plaster. Own work includes water/sewage installation, heating, electrical work, drywall, roof insulation, and the usual like laying floors and painting. We only had a permit plan signed off by an 85-year-old architect and assigned the rest ourselves. The structural builder is an acquaintance who is already building the third house in the family.
