The hole is to the left of and behind that white cabinet looking thing in the middle. Whole floor missing from that room.

Rebar may be used now but I'm not so sure it was back when this house was built, 1950's-60's? And the place has that rather "home made" look to it as though they might have built it themselves.

Building codes have not always been what they are today and in some places back then were pretty well non-existent.


Maybe it's because I live where these sinkholes just pop up or rather under from time to time that I don't find this very mysterious.
