House construction planning, realistic price for a semi-detached house?

Hello everyone,

we want to build a semi-detached house, at the moment we do not know what the neighbor wants to build.

We are thinking of about 150sqm and would like to have "real" separate walls between the houses, because we also want to play the piano or vacuum in the middle of the night, roughly speaking. Are there special insulations between the walls? And we are also considering whether it should be a solid construction or a prefabricated building... as well as the level of completion, whether we could save money through own work by family and friends...

Does anyone here have a rough estimate of the price range for this?

1.5 to 2 trillion! one two three

Hello,

the semi-detached houses in our area all have normal walls and between them there is fire protection and sound insulation. Everyone says you don't hear anything from the neighbor as long as he doesn't drill.

For a price, your information is far too vague (basement, fittings, slope, federal state, garage...) but to make it at least somewhat more concrete than my predecessor 450,000€ to 1 million.

Okay, 2.5 storeys with basement, 160sqm

Then I estimate €530,000 to 1 million with everything included.

Without knowing the construction site and your specific requirements, a first rough estimate with current prices from the forum could look as follows:
Calculate with 2500-3000 EUR per sqm of developed living space.
A utility basement of 80 sqm approx. 80,000-100,000 EUR, if you want it developed into living space, of course more expensive.
Additional construction costs between 50,000 and 60,000 EUR including earthworks and disposal.
Carport or garage depending on equipment between 10,000 and 40,000 EUR, you would need to specify what you have in mind.
Kitchen\lamps 15,000-25,000 EUR. Outdoor facilities for a small straight plot with some own work and without much frills from 20,000 EUR up to open end.
