Were you overly cautious or did you even have to provide additional funding?

Hi,
I created an Excel sheet in which I entered all the expected costs, including outdoor facilities, paving, kitchen, etc.

Then I compared all expenses against that and thus always had a pretty good overview.

That's how I did it too. In the beginning (shell construction) we saved quite a bit and further expanded our buffer. Most of it was then used up later in the interior work (more expensive tiles, different cabinets, etc.)

So don't be too happy too early if things go well in the beginning

I also made the Excel table. It looks like this for us; maybe it helps someone for orientation

Why do you differentiate between gross and net?

I also have such a summary, but it only helped me to a limited extent because final invoices were often missing and it then remained at assessments. Towards the end of the construction, it gets more interesting, because then you know that only a few trades are left, and you have to compare that with the stack of money.

You can also sweat a bit sometimes

The distinction between gross and net comes from the fact that all prices were negotiated net. By the way, I also do this professionally, calculating my hourly rate and invoices net.

What exactly does it bring you as a private individual?

What exactly does that do for you as a private person?

If you don’t like it, just pretend it’s not there.
