Division of house costs according to trades?

Hello,

is there anywhere on the internet a breakdown of house construction costs by individual trades?
Of course, only roughly, you can never say that exactly, it depends on the individual requirements.

For example:
Shell construction: 25%
Roof: 15%
Floor slab: 8%
Electricity 7%
Heating: 7%
Screed: 3%
Insulation: 9%
etc. pp.

I would be interested in that.
Maybe there is something like that somewhere.

I once saw that somewhere in a construction blog. But you can simply recreate that if you have an offer available. I just wonder what that is good for, except to be able to see afterward where most of the money is spent.

If you want to contribute your own work.

Just out of interest.

Either you are sure that you will do it yourself (painting, laying the floor, ...) or if it’s just something to consider, get a quote and calculate the material costs accordingly.
