Why building a house almost always costs more than calculated

Yes, that was more related to the fact that this is still way before the property purchase and even before the first appointment with the financial administrator. In total, a few hundred hours will certainly add up before we sign the contract for work. I also find it surprising that some people approach the topic so completely unprepared. After all, we're not talking about a new coffee machine for a thousand... But I guess everyone has to decide for themselves how well prepared they want to be.

I will never understand that... We got a quote for every little thing before we signed the loan. Then we added a bit more, and so far we are doing very well with it. And luckily there is also something like [Skonto], which adds up overall as well.

Does anyone have experience with what one should calculate for a curb drop (6m for the driveway)?

Does anyone have experience with what you should estimate for a curb drop (6m for the driveway)?

How can you ruin such a nice thread now? Please ask your question separately.

Hello everyone,

since the question about the Excel sheet came up very often, I will create a separate thread for it in [Planung]. Unfortunately, I couldn't create it right now. As soon as it works again this evening, I will link it in this post. I will then continuously update the Excel sheet there.

To what extent does my question, which has to do with supposedly easy-to-overlook (additional) costs, spoil this wonderful thread?
