ᐅ Eco-friendly Concrete House, an Affordable Basic Model

Hello,

Recently, I read this text and the life cycle assessment of a precast concrete house by Dr. Hans-Dieter Bottke, and I really liked both. What I find particularly interesting is the affordable price combined with durability and the passive house standard.
What are your thoughts on this?

Best regards,
Bottikowski

And are you Bottke or his son?

... and do you want to draw attention to yourself or your father? Or is this advertising?

Pure advertising.
The content is nonsense with extra sauce. The figures probably come out of a magic box. €15,000 (about $16,000) for a ground floor, while a prefab basement builder charges over €30,000 (about $32,000) for that. But Dr. Oetker will sort it out.

Not even a doctoral degree protects against a lack of common sense.
A silly self-promotion completely lacking in substance.

Oh, the figures might even be accurate. I would have issues with the wall construction, though. Apart from that, it’s an old concept commonly referred to as a panel building.

Panel construction style
Sky-high prices
Bungalow that first has to comply with the zoning plan / building permit requirements
Solid construction with enhanced ecological benefits
Electrical, plumbing, and ventilation systems still require maintenance.
Only maintenance on the exterior facade is eliminated, assuming there are no frost damages and the owner really likes this concrete gray.
What about flexibility?

In my opinion, this is an unrealistic project. Is there already a concrete plant willing to take this on?
How are water, electrical, and ventilation systems installed? Surface-mounted, like over concrete, or is there a stud wall in front?
Are 30 cm (12 inches) of insulation feasible because of a double-layered wall?
