Construction report single-family house 1200 €/m²

As long as the cable lengths are between 5-18 meters

Yes, I thought that too once... well, good luck then.

Zehnder gives these values generally for 75mm pipes. The minimum length results from the sound insulation requirements

Hello again

this is certainly not enough to carry out a planning that meets the requirements
and ends at the latest during the commissioning and adjustment of the required air volumes with the realization that this cannot be right.

Once again: have it planned properly in your own interest

Of course, the controlled residential ventilation was planned. I will of course do the balancing myself. And before anyone notices, in the children's rooms/office the limit value for two pipes was exceeded by 1m³. I'm going to take the risk.

Well, you do see that there are 2 pipes there, right? Or did you simply misunderstand my comment?

Hello

last attempt

I don’t know who calculated this.......
but if it has already been established that 31m3 doesn’t really fit, especially with a possibly long supply line, how then can 49m3 work on one line.


I completely agree with you on the construction costs, that can be achieved with proper discipline, good organization, and a lot of own effort.
For us it looks something like this:
Planned total costs 320k€ for about 210m2 of living and usable space - 2x kitchen 20k€ - plot 40k€ - garage for truck 40k€
plus 15k€ for changes to bathrooms and ELT
