Newly built two-family house with a granny flat

Is there then a rule about what the square meter or the cubic meter of enclosed space costs? But building without a basement, I don't want to think about it. Of course, I also do some things myself, flooring and painting work, but that doesn't help either. Or specifically, what do you think, what price should I expect?

Yes, we don't have to use the entire construction site. 11 x 11m or something similar would also be sufficient, but will it be that much cheaper?

Hello,

Yes, 3 residential units are allowed, no requirements regarding sound insulation
Budget (pure construction and incidental costs) approx. €250,000.

This is certainly a test question or an early April Fool's joke ....?

land transfer tax does not have to be paid.

Why not?

Rhine regards

Due to the possibly too small budget.

You can probably leave out the "evtl.". I'm afraid you will fall off your chair when the construction expert lists for you roughly what the whole thing would cost.

Yes, okay, we could also manage 300,000.
