Good morning, our project on site is still not really progressing and there is still no contact with the architect who is supposed to do the execution planning. But trees have already been cleared on the property and initial work to demolish the building currently on the site has begun. I would also interpret the lack of feedback regarding our floor plan changes as meaning they are not a problem.
However, I have a quick question:
The construction project is planned with a central exhaust system (bathrooms, kitchen, storage rooms) and supply air through window rebate ventilators. I asked whether a controlled residential ventilation system would also be possible and was informed by phone that this would likely be possible for an additional cost of approximately €17,000. Without having any information about the device etc. at this time, I still considered the surcharge to be very excessive.
My assumption was: exhaust ducts must already be installed, the ceiling is thick enough to also install some supply air ducts there. Therefore, it shouldn’t be too complicated.
Am I completely wrong in thinking this and is this a reasonable order of magnitude, or is someone trying to optimize their margin?
