The home is built on a fault line and was gradually collapsing with the cliff side into the lake.

Charred debris from a luxury cliff-side home fell 75 feet into a lake below on Friday after fire crews set the $700,000 retreat ablaze rather than wait for it to crumble into the water as the land faltered around it.

It took less than an hour for the fire to level the home above Lake Whitney, about 60 miles south of Fort Worth. Flames consumed exterior walls after crews spread bales of hay and fuel to ignite flames throughout the expansive home.
