I am currently working on planning the ventilation system in CAD. After that, I will design the water pipes and the drainage.

This approach aims to minimize time on the construction site and to detect errors in advance.

We also invested quite a lot of electrical work into the house ourselves. The “worst” part is that doing the work yourself means spending even more time on the construction site. As a result, you get even more ideas than you already had. At night in bed, you discover something new on your phone—something you want to have. So the next day is spent implementing those little extras. Here a wall quickly added, there a few more sockets, and a second outdoor water tap would also be quite convenient. After 9 months, I had used up my entire annual leave and accumulated 400 hours of overtime. The weekends are on top of that.

We also did a lot of planning at home in advance, but on site it’s still a different experience...

A great project for sure and good luck. Just don’t overdo it and make sure to take breaks too.

Okay... my husband and I don't have the skills for that. But I’m also glad that my husband is handling it since he provides the warranty for it.

No more lengths reach the ground floor; you need to use two ducts per outlet there.

Hello
That is probably just the cable routing.
The system design likely comes from the manufacturer or supplier.

As long as the pipe lengths are between 5-18 meters (16-59 feet), it is not a problem. And that is the case.
