Secretly built in the 1950s for government officials, this former Cold War nuclear bomb shelter was converted into a plush abode. Now known as The Glass House, this five-bedroom home in Chiselhurst was last on the market for £3 million ($4m).

After sitting in decay until 2008, a two-year renovation transformed the thick concrete building with windows, a swimming pool and an atrium-style glass roof. Not short on useful space, it also comes with a triple garage, games room, and au pair suite. Not too shabby for a former bomb shelter!

Luxurious rooms were created by carving windows and doors out of the concrete walls, then they were furnished with beautiful hardwood furniture, decorative rugs and mirrored walls. Discover automated controls for lighting, curtains and windows in the bedrooms, built around the central swimming pool. 

This former RAF base offers plenty of privacy thanks to the surrounding wooded area. The enviable central swimming pool sits in the heart of the extravagant property below the statement glass roof. Why not take a private dip on a star-filled night?

It’s hard to imagine the once cold, grey concrete building used as a shelter by government officials. According to JDM Estate Agents: "Walking around the Glass House one has to marvel at the foresight and vision of the architects and builders in turning a grey, austere and purely functional building into a fabulous luxury home to be proud of."

Once you take a look inside, you may be sad to learn that all twelve units in this converted missile silo sold out within months of being built. This somewhat spacious condominium complex not only boasts its own cinema, swimming pool and gym. The vision of engineer and property developer Larry Hall, each luxury shelter has its own digital ‘windows’ to help you feel connected to the outside world.

Sitting pretty at fifteen stories underground, this blast-proof Kansas bunker was built in 1960 to house the Atlas series of nuclear missiles. Upon entry, you’ll find the front door alone is made up of 8 tonnes of armoured steel, the 9.5-foot thick walls are made from hardened concrete and the site is protected by armed guards. Welcome home!

Twelve apartments reside across seven of the fifteen floors, with prices starting at £1.1 million ($1.3m) for a basic suite featuring three bedrooms and two bathrooms. After something a little more upmarket? One penthouse was built, complete with red leather sofas, a pool table and what looks like its own boardroom for a cool £3.7 million ($4.5m).

Not only will you find a swimming pool 200 feet underground, but this 'end of days' complex also features its own climbing wall, gymnasium and even a pet park for your furry friends to enjoy. A computer-controlled saltwater pool also awaits, for when you need to remind yourself of a little thing called ‘the ocean’.

Should the four horsemen of the apocalypse descend any time soon, you’re safe in the condo thanks to air filters, wind turbines and electricity generators providing such essential items as power, oxygen and water. You can also enjoy fresh produce from the ‘shop’ selling organic vegetables and even fish via the aquaculture and hydroponics systems installed.

Referred to as 'the largest billionaire bunker in the world', The Oppidum in the Czech Republic may just beat all other bunkers in the luxury stakes. The location of the bunker is on a strictly need-to-know basis, built between 1984 and 1994 as a joint project between the former Soviet Union and Czechoslovakia (now the Czech Republic and Slovakia).

The name originates from the Latin op-pedum, meaning ‘enclosed space’, used to describe fortresses that were constructed in Europe as early as the Iron Age. Once inside the secure enclosure, you’ll find one large 6,750 square foot apartment and six 1,720 square foot apartments with fabulous 13-foot high ceilings.

Combining state of the art security and ultimate luxury, the security director and guarantor of The Oppidum is a former Chief of the Military Intelligence Service of the Czech Republic. You’ll even find custom private vaults in which to store your precious jewels and art collections.

While keeping fit with a few lengths in the swimming pool, take a moment to admire the underground garden with simulated natural light ‘outside’ the window. After your dip, you may also enjoy the spa facilities, followed by a trip to the cinema, library or extensive wine vault. There’s lots to keep you entertained underground in The Oppidum for the impending end days and beyond.

The entire complex is operated from an underground control centre, with access to communication networks both within the Oppidum and to the outside world – something they always seem to conveniently forget to install in the apocalypse film bunkers. These height-of-luxury shelters will allow residents to survive for up to ten years, through both natural and manmade disasters, or long term power outages thanks to formidable stocks of non-perishable food, water purification equipment and even medical supplies and surgical facilities.

Recently on the market for £13 million ($18m), this Cold War-era underground family home is anything but bland. A seemingly ‘normal’ American home from the outside, the elevator down to a kitsch 1970s wonderland is hidden behind rocks and palm trees near Flamingo Road, Las Vegas.

Originally built in 1978 by businessman Girard “Jerry” B. Henderson, this 15,200-square-foot basement was designed to withstand nuclear blasts. Before creating his own subterranean wonderland, Henderson was concerned with how things may turn out after the Cold War and campaigned for underground living with his company Underground World Homes in 1964. 

Fake trees, artificial grass and day/night simulation lighting (complete with twinkling stars) creates a surreal aesthetic. A 360-degree mural provides the illusion of an outdoor landscape in the garden area, complete with putting green, swimming pool and Jacuzzis, sauna, dance floor and fake rocks to camouflage the BBQ, of course. Although not fully disaster-proof, Stephan Laforge of BHHS Nevada Properties said that "you could have a rave down here and no one would hear you". 

The kitsch decor extends into the kitchen, where you’ll spy a wealth of pink trim cabinetry and pink tiling, pink curtains and a pink kitchen island. Don’t forget about the toaster, which can be found built into the kitchen wall for your convenience. 

The property was passed onto a relative after Henderson and his wife passed away in the 1980s. Since then the most recent owner, who bought this spectacular abode for £2.5 million ($2m) in 2005, lost the property to foreclosure in 2012. This underground utopia is now on the market for £4.2 million ($5.9m) via Berkshire Hathaway Home Services Nevada Properties. Don’t mind if we do!

Affectionately referred to as a modern-day Noah’s Ark, this multitude of bunkers named Vivos are located in secure locations around the globe, from America's Great Plains to its flagship location in Germany. Whether you want pure luxury or bare minimalism is up to you, with prices running from £18,000 to £1.6 million ($25k to $2.2m) each. But if you’re interested you better apply fast, as applications to Vivos are increasing 1000% each year.

A grand total of 575 converted military bunkers await in the Black Hills of South Dakota. These opulent pods, neatly nestled in the soil, can house 10 to 24 residents across 2,200 square feet. The units cost £25,000 ($35k) and can be fully furnished by Vivos for between £18,000 and £55,000 ($25k to $75k).

Each underground dome can be customised with contemporary luxuries such as LED screens to give the illusion of windows and skylights. "We have all the comforts of home, but also the comforts that you expect when you leave your home," Vivos CEO, Robert Vicino told the Los Angles Times.

Vivos Europa One is the flagship 76-acre compound in Germany, carved from bedrock by the Soviets under a 400-foot mountain during the Cold War. Here you’ll find gymnasiums, theatres, bars and pools with over 228,000 square feet of living areas. If you fancy an apartment here, you’ll need a cool £1.6 million ($2.2 m) to spare. 

It is stated that more than 1 million potential underground dwellers have applied to reside in Vicino’s affordable bunkers, that once completed will be located in North America, South America, Europe and Australia. Each will provide access to underground water sources, sewage systems and enough food and supplies to last the apparent impending apocalypse.

Whilst it might not be on the market, you can still have yourself a slice of underground living in this former nuclear bunker turned cave home. Beckham Creek Cave Lodge sits naturally within the Ozark mountains in Arkansas, near the Buffalo National River and features all the high-end luxuries of a hotel.

The dwelling was originally carved out of a deep cavern in 1989 by businessman John Hays who wanted to create his own bomb shelter. Set within 260-acres, it has since been transformed into a hotel, enjoying a million-dollar renovation that involved adding geothermal heating and supplying the property with water via the natural spring found beneath the floors.

Although the 6,000-square-foot property sits 35 feet underground, it still boasts a 75-inch flatscreen TV, satellite and WiFi throughout. The site hosts four bedrooms, four bathrooms, a gourmet kitchen and a natural rock formation waterfall in the living room. Once used as a wedding location, it’s easy to see why this could be the perfect romantic getaway. 

If the stunning stalactite ceilings aren’t enough entertainment, you may enjoy the private cinema room, or the various lofts and balconies providing stunning views. To pass the long evenings, there is a fire pit for entertaining and warming up the cave's naturally cool temperature.

Finding popularity on the Netflix series, The World’s Most Amazing Vacation Rentals, you may find yourself sitting on a waiting list to stay in this cavernous dream house. In 2018 the property was listed for sale for £2 million ($2.8m). But if you fancy a small taste of the cave life for yourself, prices start at £1,170 ($1,600) a night with a two-night minimum required for weekends and holidays.
