Let's do the math: 260 m² * 2000 EUR/m² = 520,000 EUR ==> No, not realistic, especially with this statically demanding design and certainly not as a (high-quality) timber frame house

The tool currently outputs 208 sqm of living space. Accordingly, 208*2000=416K EUR would be quite reasonable. And yes, I also hope that an architect can still reduce it.

Question: what is included in the rough estimate of 2000€/sqm? Additional construction costs? Only the shell? Including sanitary, flooring, etc?

More like 208 * 2,500 € = 520,000 € plus additional construction costs...

Rather 208 * €2,500 = €520,000 plus additional construction costs ...

I had only read something about a total of 300 m² of floor area here and therefore assumed 260 m² of living space.

The often cited €2,000 per m² is of course only a rough guideline, which is increasingly rising. Especially with demanding architecture, it rises independently of market developments. For that, you get a house plus additional construction costs, floors, and wall coverings.

You have built before. And that with a prefabricated construction company. Then you must know how it works. Prefabricated construction companies have their model houses, which can be modified; if you want to build individually, you hire an independent architect and build your timber house with individual contracts or a general contractor you and the architect trust. And then you know that everything on the land side is still extra. It also says this on every second page here. You cannot take flat-rate numbers for calculations as fixed. The 2000 figure is from a 2019 account and applies to standard solid construction.

Prefabricated construction companies have their model houses, which can be modified; if you want to build individually, you take an independent architect and build your wooden house with individual contracts or a general contractor you and the architect trust. And then you know that everything on the plot side comes on top. This is also stated on every second page here. You cannot take blanket figures for calculation as set. The 2000 are in an account from 2019 and apply to standard solid construction.

That was 20 years ago now.... and I don’t want to make the same mistakes as back then. There are certainly prefabricated construction companies that plan “freely.” But with their architects. I’m clear that the plot and the garden come on top. But I was not aware of ancillary building costs and floors. Back then we paid 240K for 160 sqm. I probably can no longer use those experiential values today...... I do understand that for prefab house building there are no flat-rate values.
