Construction costs square meter price for living space and gallery

Hello,

I have already read all sorts of things here, but have not yet found an answer to the following "problem." From what I have read, you have to calculate with 1600 - 2000 euros per square meter of living space for building a house. How do you then include an open gallery in the costs? Assuming it is a city villa, the ground floor is 100 sqm and the attic has an open gallery to the ground floor living room with 20 sqm of air space. The living space of the attic is therefore only about 80 sqm. How does this affect the price per square meter? Can someone give an estimate?

Best regards
Sabine

I don't know for sure, but solely because of the more complicated statics, additional costs are more likely than with a closed floor ceiling.

Hello Sabine,

How do you then include an open gallery in the costs? Assuming it is a city villa, the ground floor is 100 sqm and the upper floor has an open gallery to the ground floor living room of 20 sqm of open space. The living area of the upper floor is therefore only about 80 sqm. How does this affect the price per square meter? Can anyone give an estimate?

The gallery is included as usual in the living area calculation; this accounts for the costs of the additional structural and static requirements.

Kind regards

Hello,
so does an airspace of 20 sqm then count just as if you had planned these 20 sqm as living space? Have I understood that correctly?

Hello Sabine,

Hello, so does an airspace of 20 sqm then count the same as if you had planned these 20 sqm as living space? Did I understand that correctly?

Yes. The gallery is de facto part of the living space.

Kind regards
