Swiss Survivors Huddle In Hobbit Holes to Escape Zombies
The Earth Houses are so called because they're designed to reside within their environment, blending into the natural contours of the land rather than merely set down on top of it. They're also covered with clumps of earth, which makes a lot of sense in terms of insulation, though such a design will clearly not fit in with everybody's aesthetic sensibilities.The zombie-escape houses are surrounded by conventional houses, which are likely to attract zombies by their very conventionality. While their neighbors are being eaten by the horde, the survivors can hide out in relative comfort, waiting for the zombie masses to move on to more obvious targets.
Because of the way the houses are built into the land, no one would spot the estate who wasn't actively looking for it.
The plot of land the Earth Houses are built on covers 4,000 square meters (43,055 sq ft), with each individual house covering between 60 meters squared (646 sq ft) and 200 meters squared (2,153 sq ft). There are three houses consisting of three rooms, one house of four rooms, one of five rooms, three of six rooms, and one of seven rooms. _Gizmag
Should any zombies stumble across the survivalist hidey holes by mistake, they are likely to stumble straightaway into the central pond -- where their loud thrashing about in the water will attract the attention of survivors. A quick double tap to the head should eliminate the immediate problem, and prevent the zombie's loud struggles from attracting others of its kind.
Finally, the dispatched zombie will be dried and ground into powder, to be used as zombie repellant. The repellant is liberally poured around the perimeter of the surival estate -- well away from the residences. This ring of protection is replenished after every heavy rain or snowfall.
A few additional projects -- such as a deep moat filled with zombie-eating sharks, and a 20 foot tall solid wall topped by a high voltage electrified fence -- should provide additional protection.
