Hello,
My partner and I are planning to build a duplex together with a couple of friends.
The two living units are not stacked on top of each other but are arranged side by side in two equally sized sections, each with its own entrance door. From the outside, it looks like a semi-detached house with mirrored halves. Each half spans two full floors plus a converted attic. Inside the house, there is a shared utility room, which is proportionally deducted from each living area and accessible from both sides through a door.
There is a single heat pump serving both halves.
I’m interested to know if anyone has experience with a similar project. We have several questions regarding the partition plan, deed of division, and condominium declaration.
In order for each household to secure its own financing, these matters need to be clarified beforehand. From what I understand, the architect must submit the partition plan at the same time as the building permit / planning permission application, but I might be mistaken?
We are also concerned about separating the heating and water systems so that each party can be billed accurately for their individual consumption.
I would appreciate any experiences or advice on these topics.

useful for whom.Mainly for you. Because you will likely get good advice on what might not be so ideal in your plan. Are you building mirrored on both sides?

But basically, both successful and unsuccessful examples (and everything in between) can at least serve as a reference for others.https://www.instagram.com/11antgmxde/

Exactly, I am already right in the middle of it. The screed is currently drying and I’m setting up the heat pump. I poured the foundation for the heat pump last week when temperatures were above freezing. As I said, I can gladly start a separate thread to present the project. It’s definitely quite interesting since there’s a lot of self-performed work and all tasks are self-managed (the architect is involved only in phases 1 to 4). Today won’t work anymore—I have to go straight from work to the construction site, and then the day is over, but maybe this weekend.

I can certainly share the whole process if anyone is interested or if it might be useful to someone.I wouldn’t do it. Of course, people tend to push you because they are curious as well. But often you end up losing confidence in your project because many overlook the fact that it is already under construction and criticize without consideration.H

No, he said he was already in the finishing stages. But basically, both successful and unsuccessful examples (and everything in between) can still serve as a reference for others.That doesn’t sound that way to me. Or did I just miss it? But now I have noticed it too.

But now I’ve noticed it too. @Teimo1988 is a fellow participant who kindly offered to share updates on their planning, which for them is already at the “fallen dice” stage (which is probably why Yvonne fears the frustration potential of the wedge classes for him if he still shares his planning); @Waldrich, as the original poster here, would be another potential beneficiary of this report. So these are shoes from two different pairs.
