One major issue orbital space habitats will face is the need to build a large amount of houses and other building quickly and at reasonable cost. The video below illustrates the use of so-called Habiterra bricks.
As shown in the video this bricks are a bit like Lego™ blocks and could be used to construct a wide variety of buildings. Rubble resulting from asteroid mining could be used to make such bricks, further reducing costs.
According to the website of Habiterra, using these bricks has the advantage that it does not rely upon skilled labor. This allows space settlements to utilize all of the available workforce for this massive construction efforts.
