ᐅ Are additional costs for lime plaster instead of gypsum plaster realistic?

Hello everyone,
We have received a quote for a turnkey solid construction house. For an additional cost of about €13,300, a two-layer lime plaster would be applied inside instead of the standard gypsum plaster. The first layer would be a base lime plaster, and the topcoat would be a trowel finish plaster with a grain size of 1mm (0.04 inches).
The entire house has a gross volume of 878 m³ (31,000 cubic feet). This type of plaster would be used in all rooms except the utility room, technical room, and pantry, which together amount to about 50 m³ (1,765 cubic feet).
Is there anyone who can estimate whether this additional cost is realistic or significantly overpriced?
Thank you in advance.
Good luck

This is probably because we (in this case ME) are laypeople and might fall for the sales arguments (although I can’t really say that anyone tried to sell this to us). It is increasingly promoted that these materials are more breathable and regulate moisture better. Then there’s always the magic word "mineral-based." We have now specifically asked about the additional costs for us. They come from the material being somewhat more expensive and the plaster being applied in two layers (meaning more labor). Additionally, this version would be executed in Q3 instead of Q2. We have also talked to many other homeowners. Most younger ones and basically all homeowners around my parents’ age use gypsum and are happy with it. In the end, I think it’s always a matter of weighing the options. For us, the additional cost is simply too high, so we are sticking with gypsum. Gypsum is also a purely mineral-based construction material and regulates moisture. Breathable—where exactly is anything supposed to diffuse to? Into the masonry? And then what? Will the house start to sweat?

Does the house start to sweat then?That’s a funny idea. The material can absorb water and acts like a reservoir – regulating moisture in this way. It takes in some moisture when the humidity is high and releases it back when the air is “dry.” However, you won’t see any sweating or steaming. The effect is a more consistent indoor humidity level – which is comfortable.The effect is very minor...
Exactly... it’s just a nice marketing story to make people believe they’re getting a better indoor climate… as long as enough people are willing to pay for that belief…

Many of us will have both types of plaster in the same house – gypsum in the living areas, lime-cement in the bathrooms. Honestly, who really notices the difference? I don’t notice anything.
