Cost of a single-family house with a garage - Is there a rule of thumb?

Hello!

We are planning to build a single-family house with a garage in the near future. Can someone help me with the cost estimate? Is there a rule of thumb?

Data: approx. 185 sqm living space on 2 floors, no basement, solid construction, no major extras, heat pump heating.

Thank you!

1600 € * 185 sqm + 55 K€ ancillary construction costs + buffer = ~350 K€
It worked out quite well for us...

1,200 - 1,800 EUR (depending on equipment) per sqm as a very rough estimate. Or 300 - 500 EUR per m³

Whether that's accurate or not, I can't tell you - but I have also been reading up on it recently and these numbers have come up quite frequently. However, it always depends on the house you want to build and to what extent the house can be realized on the property.

Thank you! Are these gross or net prices? Is the garage already included (ancillary building costs) or just the house?

My researched prices are all net

1200 is nonsense... It exists, but with cheap you pay extra, either with the basic equipment or later with the Spartan execution. 1600 per square meter is currently realistic, ancillary construction costs come on top, additionally garage, extras like [Wintergarten], garden and paving. That of course included, we are not a company after all ;)
