Build a house from the roof down

Skanska building houses from roof to ground. They start with the roof - and then they add the top floor, and then they continue downwards until they have a complete house. An interesting concept with a lot of advantages. Like not getting any rain inside the house. And the workers do not have to work high up in the air. Not even when they work on the 5th floor....
