Once the concete has hardend, the bladder can be removed as in the picture below.
The next step is to frame the windows and...
and then the doors as shown for Dome 8 in the foregroud.
Finally, the carpenters are hangng the door.
Nice and white, to reduce heat absortion. Notice too, the ventilation in the roof.
These will provide excellent shelter, at a minimum cost, for our loved ones.
