How much is normal to pay to finish a new house?

We’re looking for houses and were budgeting for how much a new house costs to finish/be ready to move in. The houses we’re looking at have a livable footprint of 150-200m2.

These costs are before furnishing and any specific interior additions, things as ventilation, various tiles, flooring, etc.

For this footprint, there are basic quotes in the pre-contract for all of the above, adding up to 100-150k+

Is there a baseline number per square meter I could use?
