Quoting 

The house, with its movable walls, has only one entrance, which is located on the second floor after crossing a drawbridge. Seems like the perfect opportunity to use a flamethrower and defend the life of your family, while stylishly nesting in a piece of architectural elitism.

The house is not well construed, I am afraid that it will attract all sorts of zombies eager to prove that it cannot be defended.

I can see how this one ends. The zombies will somehow make their way to all that exposed glass in the back while the family is partying away, thinking they're safe.

If zombies don't find anyone to eat... do they starve to death

Actually , it would a good house to have in Houston during the hurricane season.
