Like a vacuum jug, where the external container is not in touch with the internal one, the construction of the passive house will consist of external walls and internal walls which are not touching each other, i.e. there will not be thermal bridges. It will be built in 3 steps:
1. step: the construction of the external walls
2. step: the construction of the internal walls and the insulation of the space inbetween the external and the internal walls
3. step: the construction of the cellar floor (internal floor)
The external walls are at their definitive height and almost ready for the next step
The internal walls are out of gas concrete as well as the bearing walls
The cellar floor is covered with a 6 cm thin layer of concrete
