How to track a sinking house?

Hello, I have a small holiday home.

Due to the increasingly drier summers, the ground under the house dries up and the house sags to one side.
I would like to measure how the house sinks over a longer period of time (a few month).
Do you have an idea how i can track it and track it via home assistant? Are there any sensors that can be used here?
