Additional costs due to incorrectly planned ventilation system + floor-to-ceiling windows?

Hi, first of all, thanks for the numerous responses.

What just came to my mind and why I’m mentioning it right away. Our house itself was also "planned incorrectly," meaning the north direction on the plan does not correspond with the plot. So the house would need to be rotated 90 degrees.
Do you think they would charge us extra for that again?

How big is a "normal" window actually? I mean in terms of width compared to our floor-to-ceiling windows.


Where did you get your door from? I’ve been searching online all the time but can’t really find anything. Especially since I don’t know what to look out for. Many have their own "security" labels -.-

If you want to get the front door yourself, what should you pay attention to? The size including frame and more or how do you make sure the mason leaves the right hole in the wall?

Would you say that the Novelan LAD heat pump is better compared to the Rotex and that the additional cost is worth it?
In which ways would it be better?

Theoretically, you could also swap the ventilation system with the Rotex heat pump, right? At least in terms of space.
The plan shows some strange circles on the left and right, but in reality, it’s only 60x60
in size and would thus fit into the upper right corner. The outdoor unit could then go outside toward the street side.
Then the ventilation system could go to the old Rotex position since it’s "just hoses" that are routed outside, right?


You are absolutely right, but unfortunately, you don’t think of so many things before signing and only come to them little by little the closer the house building gets. =(


Double-wing windows don’t work that easily. First, of course, because of the money, but more importantly due to the KFW standard. If we took double-wing windows, we’d have to change quite a bit in the house to keep the KFW standard and that would become even more expensive.
Not to mention that my wife doesn’t like double-wing windows at all.
We have already been to a prefab house center around the corner from us (Mannheim) several times.
They had some rooms with just one floor-to-ceiling window.
Theoretically, it would be enough, but it always depends on orientation and such.
Maybe we should have a quick look again.


That’s true, I also asked everything in writing, but unfortunately, there were often answers just by phone... allegedly easier to explain. In hindsight, you could interpret it differently now.

I’m attaching a site plan as well. But unfortunately, the garage cannot be done differently =(


Since the standard is a plastic door, I assume the colored one is also a plastic door. I also think it’s only colored on one side because the windows are only colored on one side too.

Quickly back to the orientation of the house and thus to your answer ypg ... The children’s rooms would actually be in the south, slightly southwest, and the master bedroom and bathroom correspondingly in the north.


Site plan attached. According to the house construction contract, the following applies:
To exclude sound reflections, a distance to neighboring buildings in a purely residential area of at least 10 meters must be maintained

If you rotate the house, the connection lines change. That can cost more or less; in any case, a change generates additional planning effort (cost). But how could that happen in the first place?

I know that. I like to write an email after phone calls, something like "Thank you for our phone call today. We came to the following conclusions: ...". Short and concise. I have to do that because I'm forgetful. Besides, then you immediately have a record (who writes, stays) and both sides have the same level of knowledge (of course only if the other reads the email).

Well then, everything is fine for now. The documents will only be finalized after the planning meeting. So you can still happily make changes during that appointment. We moved our walls, altered the roof, and added windows unplanned. Only after that will the structural engineers and others sit down to examine everything closely.

OFFTOPIC, but I can't help myself: Nice thread I'm glad we're building with an architect and don't have exactly this kind of stress..

I got the door from a nearby window and door dealer near Koblenz. I think that’s too far for you, but if needed I can send you the contact details via PM.

Since we ultimately decided to build with an architect, I can’t tell you exactly how it works with prefab house companies and self-procurement. But it could be that they don’t want to give a guarantee on the blower door test afterwards because they didn’t mess everything up themselves...

However, the process will certainly be the same. You get offers and determine the width of the door. You then share this width with the prefab house company, and they have to make sure to leave approximately that size as a hole in the wall. As soon as the shell construction allows it, the door dealer will come and take measurements. Since nothing should really change from that point on, the door will fit into the hole.

You should, however, pay attention during installation to ensure the installers also adhere to the appropriate floor structure. With us, everything was simply wedged up against the ceiling, and in the end, we had the door 2 cm higher than we wanted. We were then given the choice between a new installation and a price reduction. Since the screed was already poured and the door’s electrical wiring was in the wall, we took the money.

Regards Michael

We had also considered building with an architect. However, we did not want to have to pay money each time just to find out what it would cost us.
