This leaves me with three questions:
-Is the tunnel end-chamber still on his own property? In most countries, it is illegal to extend anything on your property over the boundary with your neighbour. This applies both above ground (tree branches, parts of tall buildings) and below(shit like this). I can totally see a turbo-autist like this one dismissing such legalities as a bagatelle.
-How deep is the end-chamber and what is its purpose? It looks like a bomb shelter of the sort being touted in the 1950s, but done a bit better, (depending on the depth it is at, of course).
- just by comparing the cavity struck with sinkholes I've seen makes me think that this area is seismically unstable (this would be known by the local authorities and usually shows up as a prohibition on new construction and excavations in that area).
*OHS: Occupational Health and Safety (Act). A law with regulations intended to keep workers safe on the job.

Note: I ran this past an engineer I know who's worked in mining for his whole life. He said that this looks like an isolated limestone cavity, but could also be part of a cave system, depending on the depth. Whichever it is, he said that merely draining the water is not sufficient and the cavity roof needs to be shored up to prevent possible later collapse, and called the passage an "OHS* nightmare". He also warned that almost all of his experience was from working with granite at >1km depth and suggested getting a geological opinion.
