ᐅ Additional Costs / Extra Charge for Taller Windows

Hello dear forum members,

In the scope of work description of my GÜs, it states that windows up to a maximum size of 2 x 2.25 meters (7 x 7.4 feet) are included as standard. The number of windows does not matter, as long as the structural engineering allows it.

Setting aside the economic practicality of this rule, some questions have arisen during the planning phase:
It now looks like we will have a clear ceiling height of 2.7 meters (8.9 feet) (depending on cost calculations). The architect recommended opting for window heights of about 2.32 meters (7.6 feet).

1. Question: Does that really make such a big difference?
2. Question: What would be a reasonable surcharge for 4 floor-to-ceiling windows?

Thank you and best regards,

Tolentino

P.S.: If interested, here is the house planning thread; from the linked post onward it becomes interesting due to current updates.

Thank you for your assessments.
I hope he still comes around, or that it turns out the 800 euros are for fully smart roller shutters that automatically provide shading, made from the best aluminum, etc. Then it might still be worth considering whether to keep or discard them.
We’ll see.
I have already asked for a calculation on the removal of the windows.

What is the size of the rooms in square meters?
Currently, our kitchen, dining, and living areas are about 80 m² (860 sq ft) with a ceiling height of 2.50 meters (8 ft 2 in). I find that perfectly fine.

If you have not yet received a window position designation, I am afraid that the next trouble might arise with the crediting of the trade…

wow, that’s significantly more than what we have. I don’t see a problem there. However, our open-plan space is rather narrow (10.5 x 4 m) (34.5 x 13 ft).

yes, I’m secretly expecting that, but he can’t just cause me trouble so early in the project. Hope dies last...

So, here’s an update as well.
I’ll just quote myself:

I will probably remove the windows and do it with my father-in-law.
In the end, with the credit amount, I get all windows in RC2 (which automatically also means better soundproofing) with external roller shutters on the upper floor and Venetian blinds on the ground floor.

The credit was surprisingly high, and with it, I was able to get significantly more included for roughly the same price through my father-in-law’s former employer.

Now a different question:
What exactly do you need to consider for the handover?
My father-in-law said the rough opening dimensions are mandatory, and a smooth plaster finish. Anything else?
I have already clarified with the general contractor that there will be a construction pause until the windows are installed, and then they will take over again. After reading about the forgotten connection, I am a bit cautious—so is there a standard (e.g., DIN) or something similar that specifies which trade is responsible for which work?

Thanks and best regards

Nominal dimensions are nice, but actual dimensions are better. Regarding the quality of the reveal, you should not only ask the installer what they need but also the general contractor what they usually provide for their regular installer. The more these differ from each other, the more carefully you need to ensure that any agreed deviations are properly implemented. Be prepared to personally (and your construction supervisor) specifically check this at the handover stages.
