It’s a gigantic concrete monolith on the outskirts of Warsaw, Poland, with sliding exterior walls and an aluminum rolldown gate made by a company that normally supplies shipyards, according to the website of Polish architecture firm KWK Promes.

The home was built for clients whose “top priority was to gain the feeling of maximum security in their future house,” the website says.

Take a look inside.

The Safe House appears to be a solid concrete steel block from the outside.

The house took three years to build and was completed in 2008.

As if the compound wasn’t secure enough, the home is also surrounded by seven-foot-high sliding walls.

The walls can be electronically sealed.

The concrete slabs open to expose windows, and an aluminum grate rises to let sunlight in.

It can transform from sealed fortress to inviting home with just a few quick maneuvers. 

When the walls and shutters retract, the revealed structure looks more like a modern home.

“When it shrinks you can say it’s ugly, it’s a block,” architect Robert Konieczny previously told Insider. “But when it opens, it becomes a friendly, nice, interesting building.”

The sliding aluminum gate doubles as a movie screen.

It may be made of concrete, but the interior is light and airy.

The interior was designed by Magdalena Radaloowicz-Zadrzyński. 

Floor-to-ceiling windows provide stunning views of the Polish countryside.

The house is surrounded by trees.

The space features both indoor and outdoor dining areas.

In the event of a disaster, the outdoor seating would be protected behind the house’s metal walls.

The house also includes a swimming pool.

With a movie screen and a swimming pool, the Safe House is great for entertaining.

The pool can be enclosed in giant metal walls in case of a zombie apocalypse.

In the event of an apocalypse, residents will still be able to take a dip in the pool.

A drawbridge leads to a roof terrace above the pool.

The bridge retracts into the surrounding concrete. For security purposes, the only available entrance to the house is the front door.

The yard includes outdoor seating.

The lawn chairs are shaded by a patch of trees.

There’s even a small garden with a fountain.

It’s a calming oasis nestled inside an intimidating structure.

At night, the Safe House is bathed in warm lighting.

The structure is well-lit.

Who knew zombie-proof homes could look so good?
