Monster House(2006)

The house that is eating everyone that comes to its front lawn is actually the spirit of Constance.

Constance was part of the freakshow in a circus as the largest woman alive and fell in love with Nebbercracker (the guy who owns the monster house). They get married, and Nebbercracker vows to build a house for his new wife and begins to build it.

After a freak accident, Constance dies as she falls straight down into the basement of the unfinished house, which is filled with cement, burying her alive.

In order to stop the house from eating everyone on Halloween, Nebbercracker needed to destroy it before the holiday came around. Chowder, DJ, and Penny help him by bringing the house to a drained lake area where a new tower complex is being built DJ throws a dynamite stick into the house’s chimney, and it is finally destroyed, freeing Constance’s spirit.
