Why do houses remain upright when they are floating off their foundation?

Question

Here is a video where the house remains upright: https://reddit.com/r/WTF/comments/gvzt1e/landslide_in_northern_norway_3rd_of_june_2020/

I figured that the house would have a high center of mass.

The house isn’t floating off its foundation in the video, the whole landmass is being sucked into the water, along with the house’s foundation.
