This seems like a great place to make a last stand when the undead rise. It’s designed by Polish firm KWK Promes and is called the “Safe House.” It features an indoor swimming pool and a large windowed wall that opens onto a second-floor balcony.
If zombies come, the whole thing folds up into a giant, impenetrable fortress of concrete accessible only through a second-floor entrance that is protected by a rising drawbridge.
Here’s a more detailed description of the house:
… located in Warsaw, Poland … the most distinguishable element of the design is the moveable exterior wall components that allow the house to be completely closed to its environment or open and connected to the rural landscape. while the initial read of the design might seem confining, the house, when in its open state, offers immense transparency while establishing a strong relationship to the site.
… mobile elements include large ‘shutters’ which essentially are hinging exterior walls ranging up to 3.5m in length. a drawbridge from the upper floor provides access to a roof terrace above the swimming pool. all the moveable components are mechanically operated with built-in electronic engines.
… the cuboid building is a concrete monolith, while its non-fixed components are composed of light steel trusses filled with mineral wool to ensure complete insulation. All exterior surfaces are clad with cement-bonded particle boards.
