Rob Zombie's New Crib's Big Enough For 1,000 Corpses

Rob Zombie and his new Hollywood Hills pad go hand-in-hand because they're both full of heavy metal.

TMZ has learned ... Rob threw down $2.49 million for a mid-century hideaway that looks like it was built just for him.

It's 2,300 square feet, but only has 2 rooms and 2 baths. While the place is dark, there are plenty of un-Zombie like features ... like a koi pond, pool and outdoor patio.
