ᐅ Additional Costs Due to Incorrectly Designed Ventilation System and Floor-to-Ceiling Windows?

Hi, we have our final planning meeting on December 13th, after which everything will be sent to the building authority (building permit / planning permission).
From the beginning, I told my salesperson that the outdoor unit of the Rotex ventilation system was incorrectly positioned in the first offer. The layout shown is not possible because the garage is supposed to be there.
I was told, "No problem. This can be changed in the planning phase and moved up."
Now I wrote to the CEO to have this corrected.
The reply was only:
On your floor plan, you moved the outdoor unit of the heat pump to a different location. This is not possible with the contractual Rotex heat pump. A Novelan LAD heat pump is required, and the outdoor unit must be moved further to the right, against the outer wall of the study room.
Here are the costs: Change to Novelan LAD + 2,138.00 €
Extension of the outdoor unit + 1,509.00 €
The reason is that the outdoor and indoor units have to be aligned at the same height/line.
Of course, I disagree with this.
Do you have any suggestions on how to solve this without extra costs or significant loss of space?
The pantry shown in the picture will be removed, and the utility room (HAR) will be made larger instead.
Point 2:
I wanted to replace the two large floor-to-ceiling terrace windows in the kitchen with one standard window, because the kitchen island will be placed against that wall.
Reply:
– Changing the floor-to-ceiling windows in the kitchen to standard windows with a masonry sill is possible at the same price in the project planning.
Question: By “standard” you mean? So two large floor-to-ceiling windows cost the same as one normal window?
Point 3:
Colored front door with a small side panel, ADDITIONAL COST 1,464€???? That seems quite high for just a bit of paint or finish, right?
Point 4:
I want to install a horizontal window at the top of the hallway to bring light into the room (we don’t want double casement windows). We saw this in a prefab house with the same knee wall height as ours.
Reply:
In the current plan, the window is not possible because the wall height is insufficient. Otherwise, the window would have to be fixed and equipped with TRAV glazing. The cost would be around 1,400.00 € to 1,600.00 €.
What do you think?
Point 5:
Price reduction for removing the standard front door: -1,315.00 €
But if I want an additional door, it costs me over 4,000 €. How is that possible?
See the attached picture.
Maybe they want to remove it because the door is not good enough — no RC2 rating, no windows with privacy glass, etc.
Here is the description:
Your contract includes a white plastic front door from the standard range with a small side panel.
The side panel has clear glass; satin glass can of course be added separately.
The front door has basic security, which should correspond approximately to WK 1, but a higher standard is possible and can be arranged.
According to the contract, a handle about 30 cm (12 inches) long is agreed.
Point 6:
Are the floor-to-ceiling windows on the upper floor acceptable? Or do they let in too little light?
Would a standard window be better? What is considered standard? What size is that?
So, that’s it for now. I actually wanted to write very little, just one or two points.
Thanks

Unfortunately, I don’t know who will be installing the windows and doors =(.
Maybe it’s possible to find out. But I think they’re really fed up with us by now.
Question about the heat pump.
I’m thinking we’ll go with the Novelan, simply because I’ve only read bad things about the Rotex earlier.
With the Rotex HPSU Compact 308, I get a hot water tank of 300 liters (79 gallons).
With the Novelan LAD 5, it’s only 180 liters (47 gallons).
Is that really enough? Two adults and one child. Another child is planned, so it will be a household of four.
We also have a ventilation system with heat recovery from Pluggit, the Avent ventilation unit AP.
Novelan offers a combined module called the “Luftstation,” which includes a domestic hot water tank and a passive supply and exhaust ventilation unit with heat recovery.
Wouldn’t that be a better solution for us?
First, it comes from the same manufacturer, so not two different systems, and second, it saves space because there wouldn’t be an extra unit to install, if I understood that correctly.

And what about the 180L (48 gallons) hot water storage? Isn’t that too little?Not necessarily. The storage temperature is higher than the desired temperature at the outlet. That means the water is mixed down. It certainly depends on the number of people, their shower/bath habits, and how long the heating system takes to reheat. With gas, I wouldn’t worry about it at all, and a heat pump can activate an electric heating element if needed—basically working like a tankless water heater—so hot water is guaranteed, but with lower efficiency and higher operating costs.
We currently have about 170L (45 gallons) in our gas boiler and have never had issues with cold water, even when we have guests, despite using a rain shower.
