Ok so they made an house of concrete. It’s going to be so cold and damp, but very strong.

Many places in the world use concrete as the primary building material.

Also the windows look like they are on steel frames. That will work well with thermal expansion.

Again, not an issue in many parts of the world.

And the roof is taped on?!?!

It’s under construction. Temp solution to prevent rain from entering.

You’re being very critical of something you have no knowledge about.
