How much building material is needed?

The amount of building material starts with the decision how many floors to build. The step from just the ground floor to the first floor is a huge leap.






A lack of footfall sound insulation is something for which a building owner is cursed even after decades. So that you can hear no one walking on the floor below, you take a prestressed concrete ceiling, footstep sound insulation and screed on it and then the floor covering comes. This means you are over 400 kg per m².

You can't just put this on a few ground anchor. During the planning of GEMIN 66-105 I was at 30 m³ concrete with 70 tons weight for the foundation. Together with prestressed concrete and screed for the floor of the 1st floor already over 100 tons.

GEMINI next Generation - energy + food + living comfort GEMINI next Generation - energy + food + living comfort
What can housing cost? Where can you build? How much Energy should a house produce? How much building material is needed? GEMINI n.G. is looking for completely new answers to these questions.


Prehistory of the GEMINI next Generation project
It started in autumn 1991 with the GEMINI habitable solar power plant, 2011 with the initiative Solar Building Land and 2018 with GEMINI 66 - we build our house ourselves.


Where can and should GEMINI next Generation be built? Where can and should GEMINI next Generation be built?
Using existing land better and building where conventional houses cannot or are not allowed is an important objective of the GEMINI next Generation project.


How much energy should a house generate? How much energy should a house generate?
As much as possible! Because we need to get out of oil, coal, biofuel, natural gas and uranium. Our houses should contribute as much as possible.

How much can living cost?
This is not only a question of existence for the individual, but also for society as a whole. The competitiveness of the national economy is destroyed by high housing costs.
