KWK Promes, an architecture firm in Poland, calls the concrete house with movable walls “The Safe House.” It’s located in a small village outside of Warsaw, and is as elegant as it is secure, with glass walls throughout when the concrete slabs are pulled back.

Over 8,000 square feet, it’s built for real world protection, According to the KWK Promes website, “the clients wanted the feeling of maximum security in their future home.” After crossing an outer gate, visitors have to wait in a “safety zone” before concrete slabs are moved to let them in. Additionally, there’s a drawbridge that leads to the swimming pool.
