Construction costs: Single-family house in Baden-Württemberg 2019 (KFW 40 plus)

I have rarely heard such sayings about 230sqm of heated living space lately...

This is called loss of reality and is not representative. I still think it's good. However, I myself would not build so large even if I had 100k€ more budget. Such a thing is unmanageable without a cleaning lady.

I'm more concerned with the converted space, not the heated area.

...and the difference lies where?? In the ceiling height??

Then it's just 1000 cubic meters... that's not little.

And if you turn the basement into a granny flat then it's also 230 sqm.

You simply have no connection to reality!

That is called loss of reality and is not representative.

LOL then just drive through our new development area. Most of them probably suffer from loss of reality there too...

But I also don't understand how you can discuss a relative size for so long...

If the trend continues like this, we will soon live like the Japanese in 2 sqm rooms

Oh, I would have preferred to build 250 instead of 170. If you can afford it, it's okay.

Sqm is not a relative size. They are what they are.

And the statement about loss of reality was not referring to the fact that people build over 200 sqm but to calling approximately 230 sqm of living space not large.

Assuming 3-4 occupants that would mean 50-70 sqm per person... that is definitely well above average.

And to contribute something to the topic, our architect calculates with 450€ per cubic meter for a good standard (about KfW 55 to slightly better, but we are building without KfW standard).

...and where is the difference then?? In the ceiling height??

I want to see the house with 1000 cubic meters and 150 sqm with a basement.
How high are the ceilings supposed to be there, 3 m clear height?

We have 1275 with a net floor area of 120 sqm per floor, with above-average ceiling height.
