solar panel?

Look at the front 2 column, most likely has no piling or footing to support the weight, once there is soil movement beneath the column will move and whole thing will collapse. I suspect the drainage which water seep into soil and cause soil movement.

For housing developer normally they do piling on the build up area including car porch, this one high chances didn't do piling on the extension.
