It depends how you look at it here.
For example (just giving average prices of what we looked at)

one half of a new duplex (two houses together) with a living area of 100m2, and a tiny yard was 310,000€.
The finished house (still needed work) 180m2 living plus a basement and garage and land - 390,000
A place like ours is 200m2 living + 100m2 basement, own land and is about 240,000-260,000 + 70-100,000 for renovation.

The new one is easy, but doesn't have much freedom and because it is shared, has additional shared costs. You also can't add value to it as it is already finished.

If our house was newly built - it would cost us around 400-600K.
