Why building a house almost always costs more than calculated

The thread title is incorrect - it should read as follows:
Why building a house with gü/bt/gü almost always costs more than calculated

And which house construction doesn't? Just don't say with an architect now

Furthermore, the following important reasons are missing: - Stinginess (regarding the control of contracts and a [bqü]) - awg - sugarcoating and ignoring defects/problems until there is no other way - Laziness/Ignorance/Stupidity/awg/Naivety to familiarize oneself with the subject as a builder and to face one's own responsibility as a house builder

And which house construction doesn't? Don't you dare say with an architect

In that case, the reasons for cost increases are often elsewhere and have not been listed. In the renovation of old buildings, there are again other important reasons.

You do have demands - which you of course fulfill all by yourself, right?

That was a joke from him..

With architect, it ends like with [BER]
