Simon Marks, 37, thought he had driven onto flowerbed when the wheels of his car got stuck in a hole…

Looking at the damage he’s done on his car he though “well, this day couldn’t get any worse.”As he was about to take a closer look to the damage, he heard the sickening sound that made his heart race. What the hell was that?

Watch the tour of the shelter:

Kneeling down to take a closer look, Simon saw that the pavers of the driveway had cracked, and then right in front of him, the driveway began to give in.

The pavers kept on cracking with an eerie sound, and it opened to a whole new revelation.
