Floor plan design single-family house (city villa 140 sqm) on a slope with double garage

Go back and add everything up for yourself. Then write down the total you come to and what you left out/added in.

I already told you what you have to calculate with and what you can exclude. My calculation also includes 2 levels of 65m L-stones at 80-100cm with terrain modeling! This fun costs me about €30k gross

Can you tell me that again including terrain modeling? There is so much written here that I have lost track of what is necessary and what is not. Thanks!

You calculate 2000/sqm just for the house.
As someone from Lower Saxony/Northern Germany, you are somewhat cheaper... however, these prices have been quoted for a year now and costs are constantly increasing.
I would at least plan for that.
Additionally, there are 25000 ancillary building costs, in your case I would add another 30000 because of the slope.
Paving another 10000, carport 5000, painter/flooring 10000
Of course, everything can also be done in the cheap range, but I would calculate with average values.

Kannst du mir das noch mal nennen incl. Geländemodellierung? Hier steht so viel drin das ich die Übersicht verloren habe was nötig ist und was nicht. Danke!

You absolutely have to deal with it yourself in order to get a feeling for it.
And searching through your own thread is the lesser evil, I would say.
You should form your own numbers, otherwise people tend to underestimate the costs.

If I now exclude my basement. You should come to around 380k€ for 139sqm somewhere with double carport and terrain modeling + ancillary construction costs. Possibly plus 10k€ due to the more massive base plate because of the slope. Without kitchen. But 380k€ would be what you could orient yourself by.

If I now subtract my basement. You should come to around 380k€ for 139sqm somewhere with a double carport and terrain modeling + incidental building costs.

Ok, I roughly calculated with 350k€ but thanks for that!

The living area should be about 140 sqm, preferably "a bit" less. I originally just wanted a rough value, because you also wrote here that in the end the prices also depend on personal taste - e.g. wooden stairs or glass stairs! But now there should first be a rough floor plan, right?
