It has deep point founding columns rather than a shallow uniform slab, it can calibrate its height hence having some kind of hydraulic system on top of it. In the most difficult part of construction, the foundations, this building is more complex than "a normal house", the separating elements like internal walls, windows, floors and furniture comes secondary as they are prefab and can easily be put together but that insulating black paneling (and the one under it) i suppose can only be transported via truck or airplane due to its weight.
All done under -40 celsius so the workers were using some sort of suit that hampers their mobility significantly, i mean it can be done but it's one of the most hardassed constructions i've heard of, it's like building a rig in the middle of a hurricane alley part of the ocean with a thousand kilometers without contact on any X/Y/Z coordinate.
