In Jesus' parable, what happened to the house built on sand in the storm?

Answer: It fell with a great collapse

The foolish man who hears but does not act is like one who built on sand: the storm beat against the house, and it fell.

“But everyone who hears these words of Mine and does not act on them is like a foolish man who built his house on sand. The rain fell, the torrents raged, and the winds blew and beat against that house, and it fell—and great was its collapse!””— Matthew 7:26-27 (BSB)
