Best zombie defense

Post a pic of a building, house or landscape that would be perfect for zombie defense.

My first attempt. http://26.media.tumblr.com/tumblr_l30etufgrQ1qb62c4o1_500.jpg

If I knew they were coming 4 years before they struck I would dig a giant and wide hole with a digger build a bunker then fill it back in with dirt. Or take over an existing bunker.
