That house isn't designed to withstand a lahar, or the glass doors wouldn't be at ground level. And there's plenty of houses that can easily withstand heavy rainfall...but again, a door that close to ground level isn't a great design. I'm not really sure what kind of disaster this is good for - sure, the metal can probably survives, but as I said before, it sure doesn't look ready to protect the inside.
