Strangely sustainable, this towering haven is designed to turn the energy of the undead toward a positive purpose, using zombies to turn a turbine in order to provide both power and water pressure in case of a viral apocalypse.

As part of the Zombie Safe House competition, this Zombie Ranch entry goes above and beyond simply protecting people from risen corpses, turning their lust for blood and brains into a baited trap to keep life going above the ground.

The slow-moving zombies push a twisting turbine that sends water up for drinking and farming on a second story – residents occupy the top level, presumably for an extra layer of safety and to get some distance from the groaning hordes.

A series of spiral staircases and drawbridges provide ways to cut off attacks on each floor as well as a means of lifting the entire structure further skyward to make it less accessible when a swarm wanders through.

Each zombie-resistant tower is designed to be fully self-sufficient so survivors can remain aloft indefinitely, leaving them free to enjoy the end of the world in relative luxury.
