Expected construction costs in Hessen: architect vs contractor

Without wanting to offend anyone, I read the following:

Basement 120sqm
Ground floor 120sqm
1st floor 120sqm
2nd floor 90sqm

That makes a total of 330sqm of living space and 120sqm of usable area.

I don't see anything about a garage, parking spaces, or similar. But I do read mid-range to upscale fittings.

And with 330 * 1,800 euros (so mid-range fittings) = 600k

And 100k for a basement also does not seem very unrealistic to me.

Don't be mad at me, but I don't see a 4 or 5 in front of that. With a lot of saving a 6, more likely a 7.

My opinion.

No, one floor less: ground floor 90 + 30 upper floor 120, basement and attic

The basement is clear in terms of price. And a partial basement doesn't make sense. You noticed that yourself.

I'm more focused on the attic.

He writes in the initial post 2nd upper floor 90 sqm, later as a sleeping area.

Full-fledged living and sleeping space costs money. It doesn't come for free on top .

I still read 330 sqm of living space according to the living space ordinance.
