Oppidum is a Prague-based luxury bunker company founded by entrepreneur Jakub Zamrazil.

As in many other luxury bunkers, the interior rooms are decorated with flat-screen windows, broadcasting videos of skylines and natural scenery, and often following the day and night patterns.

Pionen White Mountains was built by Albert France-Lanord Architects in a 1200 square metre former fallout shelter. The location lies 30 metres below the granite rocks of Stockholm’s Vita Berg Park. 

The Safe House near Warsaw, Poland, was designed by Polish architect Robert Konieczny of KWK Promes. Its movable concrete walls and metal shutters turn it into a fortress without doors or windows. The property is also surrounded by a concrete wall. 

Access to the Survival Condo, an Atlas ICBM missile silo that has been converted into a luxury bunker. The owner, Larry Hall, guarantees that the bunker will accommodate up to 300 people.

The Survival Condo consists of several floors with private flats. Penthouse flats cost $4 million, one-storey flats cost $2.5-3 million and half-storey flats cost $1.5-2.5 million.

Survival Condo is a small town, where the amenities are designed to keep you mentally healthy underground. The project includes a “public” swimming pool and spa, a climbing wall, a cinema, a library, a supermarket and a hydroponic organic food and aquaculture garden, a first aid medical centre, a classroom for those still studying, and a computer room with a local internet network.

Vivos Europa One, by Robert Vicino, consists of a series of luxury flats created from the gigantic Soviet bunker dating back to the Cold War near Rothenstein in Germany (former GDR). The bunker is 120 metres deep under the mountain and covers 23,000 square metres.

Vivos xPoint, by Robert Vicino, is the largest community of preppers. It consists of 575 bunkers, and is located in South Dakota.

Each bunker can be purchased for $35,000, plus an annual rent of $1,000. Buyers can choose to furnish and equip their own bunker themselves or turn to Vivos for furnishings and air filters, for an amount of around $120,000.
