Stone82Hello,
I have completed all the preliminary planning and sent all the documents to the builder.
The builder has determined that, according to the development plan, specific soundproofing measures are required for the plot.
The house upgrade includes a decentralized ventilation system, special soundproof windows, soundproof insulation for the roller shutter boxes, and a noise protection expert.
Of course, with additional costs.
However, I am not very satisfied with the decentralized ventilation system and believe a central ventilation system would be better.
What is your opinion?

What is your opinion?Are you planning the build yourself? Who is the "developer" – a developer sells you a plot of land with a new building. A general contractor (GC) builds a house on your land – but also handles the planning (whether well or not is another question).
Why hasn’t your architect noticed the “problem”?
Decentralized systems are always more prone to noise than centralized ones. Do you then have half a dozen holes in the wall where sound can come through?
Why isn’t it known in advance that a flight path, highway, or similar runs right outside your door?
Why don’t people read the zoning plan / building permit application in advance?
My opinion? Write a detailed thread with more than just that one question. Include an excerpt from the zoning plan. A printout from maps. The house plans. The exact situation of who did what when and with whom. Etc.
So far, I would personally just say: How careless can you be not to look at the zoning plan before planning?!

I have planned everything so far What have you planned? What is this about exactly?
I will translate once:
This probably means that the original poster sent their own planning to a general contractor who provides included permit planning, and during that process it was found that noise protection requirements apply to the building plot, and compliance must be demonstrated. Neither the necessary actual measures nor their assessment are included in the construction performance description.
The GC suggests a decentralized mechanical ventilation system—presumably because it costs less for them to purchase—and the original poster thinks a central mechanical ventilation system is better. I share this opinion. Technically, a central mechanical ventilation system has the significant advantage of making heat recovery easier and—assuming inclusion of all or most rooms—being more economical overall in terms of components. This apparently does not apply to the GC, who will probably offer the technically better solution at an additional cost. The downside of the central system is the ductwork that connects the system’s parts. On this, I wrote almost seven years ago
My opinion has not changed on that. However, switching to a central system later is usually more expensive than installing it from the start, so it is better to choose it as the initial equipment if preferred. In this regard, I believe the original poster is "correct."

It would certainly be interesting to see if there are statistics on the market share of mechanical ventilation systems chosen by home builders who work as commercial beverage-line cleaners.

Oh dear, it seems I made a very poor start with this thread. I will try to clarify and set things straight. I also apologize for having incorrectly defined and used the term “general contractor.”
I am in the process of building a 127m² (1,367 sq ft) bungalow with 3 rooms together with a general contractor. The house will be an EV40 house built using timber frame construction. We have deliberately chosen a window ventilation system. We can discuss later why we made this choice.
By my preliminary planning, I meant everything related to financing, kitchen, flooring, solar system, commissioning a geotechnical survey, checking if the house fits the plot, purchase, and so on.
Once I completed the initial steps requested by the general contractor, they reviewed my documents and realized that the house must be adjusted to comply with the noise protection regulations in the development plan. They informed me about this along with the necessary measures and associated costs. It was frustrating because, with all the information I had, I thought the house already met these requirements. Well, that’s why you plan with a buffer.
Background on these noise protection regulations: About 150 meters (490 ft) away in direct line of sight runs a lightly used, unelectrified single-track railway line, whose trains I didn’t even hear from the property. However, occasionally a freight train passes by, which is somewhat louder.
Among the required adjustments is the installation of a decentralized ventilation system. Before the construction meeting or the selection appointment, I want to get a clear idea of whether this is a good solution or if a central ventilation system, although somewhat more expensive, might be worth considering, as I tend to view decentralized ventilation less favorably.
I hope I have clarified everything correctly and explained it understandably. I apologize again for any confusion I caused.

Papierturm24 Jul 2025 17:52Regarding the situation: Please provide the name (no links!) of the development plan.
If it has not been signed yet (hopefully), I would also consider using a different company.
In our case, due to a formal federal road located some distance away (with very little traffic and mostly passenger cars, plus on the opposite side of the neighborhood), noise protection measures had to be implemented. These consisted of soundproof windows. However, we planned with a traditional centralized mechanical ventilation system with heat recovery.
Now, I simply do not know if the problem could lie with the originally planned ventilation system. Central window-frame ventilation is not known to me as a standalone ventilation system. If at all, I only know this in connection with exhaust air heat pumps such as the Nibe S735.
So, the next question: What type of ventilation was planned? And which one does the general contractor (GC) now intend to install?
P.S.: I always correct my wife to say "GC" or "building company" when she says developer... she doesn’t like that either...
