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.

Yes, that’s why we asked about it. But the building authority refuses to install windows above 2.25m (7.4 feet) in height, and some people here in the forum, as well as the architect, and now even us, don’t find that very appealing anymore. The room height visually suffers because the window lintel then extends downwards for quite a length.

Suggested raising it by half a brick row,
Half a brick row sounds reasonable (cost-effective, practical).

We need to finish the building permit/planning permission application to avoid losing time, and we can discuss the roller shutters later during the execution planning.
He’s trying to box you in so his pharmacy-level price becomes non-negotiable.

Right now, the roller shutters are frustrating me.
GÜ refuses to install the windows in a way that would allow me to fit the external roller shutters flush with the facade myself.
Pure monolithic obstruction. Can you still change horses? At the very least, I wouldn’t recommend him anymore.

Either that, or he needs money—the next installment would be due after submitting the building permit / planning permission application. Admittedly, I waited a bit too long to pay the first installment. Maybe that caused some hard feelings. On the other hand, I usually pay in advance up to the shell construction phase...

Monolithic pure harassment. Can you still change the contractor? At least he wouldn’t get any recommendation from me anymore.


Well, the consumer contract is signed, so if I cancel now (which probably isn’t legally justified yet), he can keep 5% without having done anything...

I would find that an overreaction as well. He also said we should maybe resolve this personally in the execution planning meeting, possibly even with the window supplier. So there might still be a chance. The only question is, are the window heights relevant for the building permit / planning permission? Or, if the approval is based on documents showing 2.25m (7.4 feet) window height, can I still change to 2.32m (7.6 feet), or vice versa? Does anyone know?

I don’t know what’s going on with the general contractor right now; they’ve always been very flexible and cooperative before.

Good luck

Oh, regarding the roller shutters:
If he insists on being inflexible about the roller shutters and refuses to compromise, I would consider removing the windows completely from the scope of work and hiring someone else (my father-in-law’s old company). Then I could also go with 2.32 m (7 ft 7 in) high windows, or even lift-and-slide doors, etc.
I actually get better prices from my father-in-law’s company.
So far, I avoided doing this only because of warranty concerns (connection tightness, etc.).
But almost 16,000 euros just for roller shutters?

Can you provide me with some arguments? Because he explicitly said that it is too complicated structurally, and that adding roller shutters afterward often leads to mistakes, so it’s better to do it all at once...
It’s really strange. On the one hand, he seems willing to include the roller shutters, but on the other hand, he makes such a defensive offer.

Building permit application)
Changing the ceiling height would be difficult due to room volume and stair calculation; changing the window height is possible as a design adjustment without any problem.
Lift-and-slide door)
I don’t see that working at 201cm (79 inches) width, only from 251cm (99 inches) onwards.
Installation level)
I don’t see any reason for a monolithic installation here; the windows can be placed exactly where they need to be for the roller shutter to fit properly. With External Thermal Insulation Composite Systems (ETICS) and especially with ETICS plus a facing brick layer, this would be much less flexible.
Defensive pricing)
He probably underestimated that: I also see room to push back on the window prices and buy them elsewhere.
