Inside The Nuclear Bunker Becoming Canada’s Strangest Luxury Hotel

Most luxury hotels sell the view, but The Diefenbaker has no windows. Hidden beneath a grassy hill in Debert, Nova Scotia, the two-story, 64,000-square-foot complex was built in 1964 to withstand nuclear attack. Its thick concrete walls and blast doors are being converted into 50 privately owned suites that operate as a boutique hotel when their owners are away.

The concept blends a hotel, a private members club, and a doomsday shelter. Guests can book an underground stay with access to a spa, fitness center, gourmet dining, a coffee shop, and a cigar lounge. Owners buy a more permanent asset: a secure suite they can reclaim if an emergency closes the hotel and the bunker returns to its original purpose.

Renovations started in 2025, and project co-owner Paul Mansfield reports that about $8 million has been invested so far. The plan is to finish the first 15 suites in 2027, with the rest ready by the end of 2028. Since the transformation is ongoing, the hotel experience, security, and long-term survival systems are still in the planning stage and have not yet been tested.

The hotel program stands out as the most unique part of the business model. When owners are away, their suites are available for booking, and the revenue is shared between the owner and the developer. If there is a real emergency, hotel guests have to leave so owners can come back. Most of the time, it operates like a luxury vacation rental, but the main reason to buy a suite only becomes clear if an emergency actually happens.

There are 50 suites, split into two types. Palisade Suites are about 300 square feet and work well for one or two people. They have 14-foot ceilings, a private loft, and their own climate controls. Martello Suites are larger at about 600 square feet and can sleep up to four people. These also include lofted storage and extra room for custom interiors. Buyers can combine neighboring units and pick their own layouts, finishes, and furniture.

Prices are not shown publicly, and interested buyers need to go through a vetting process first. According to sales materials, a Palisade Suite costs about $1.25 million, while a Martello Suite is about $2.5 million. Instead of a standard condominium deed, buyers get what the developers call a registered ownership stake in the complex.

The annual membership fee is significant: $100,000 for a Palisade Suite and $200,000 for a Martello Suite. The developers say this fee includes security, dining, medical support, and wellness services. By September 2025, the project team reported that 11 suites had sold during the early sales period.

The main challenge is turning a former government shelter into a place people would actually want to visit. The shared spaces are designed to give the bunker a resort-like feel, with a full-service spa, sauna, relaxation rooms, yoga and fitness areas, a coffee shop, cigar lounge, and restaurant-style dining. The plan also includes on-site medical care and mental health counseling, which could be especially important if residents need to stay underground for weeks or months.

To make up for the lack of natural light, OLED lighting is set to mimic the pattern of a typical day. The suites have 14-foot ceilings and lofted areas to help reduce the sense of being underground. Owners can also customize their interiors, which would otherwise look like identical concrete spaces.

Matthias Fitzthum from Bespoke Home & Yacht Security, who is consulting on the project's security, explained in our interview that the design also considers the psychological effects of long stays underground. He suggested adding large digital screens in places like the spa to show outdoor scenes. “I would open walls, virtually,” he said. The goal is to give the feeling of ocean views, movement, and daylight in rooms without real windows.

The developers expect the completed property to require about 40 staff members, plus specialists for its expanded data center. That gives the project the scale of a small resort, although the service operation must work around security procedures that are unusual for any conventional hotel.

The security plan includes biometric entry, round-the-clock surveillance, and thermal radar. The developers brought in Bespoke Home & Yacht Security, a German company known for working with wealthy clients. Their services include close protection, international extraction, armored transport, anti-drone technology, and reinforced safe rooms.

Fitzthum explains that security goes far beyond the bunker doors, starting at the property’s edge and including drones, underground sensors, and airspace monitoring. “If we turn the switch and we go for code red, then all the systems are up and running, and then nobody will be able to get in there,” he said. During normal hotel operations, some systems stay on standby. In an emergency, Fitzthum says the hotel would close to regular guests and only owners would be allowed in. “No hotel guests will be allowed, because we will bring in the owners, and we need all the capacities for the owners.”

The bunker is built to protect both people and valuables. There will be climate-controlled vaults for art, wine, jewelry, and precious metals. Fitzthum adds that secure storage will also be available for rent to those who do not own a suite. The 15,000-square-foot data center will have backup power and protection against cyber attacks and signal interception.

Fitzthum also wants owners to have the option to rent secure data storage inside the bunker for highly sensitive information. “I would keep this data inside the Diefenbaker bunker,” he said. The project now goes beyond the original building. Fitzthum explains that server operations will move to a second secure building nearby, which will eventually be connected by an underground tunnel. This change will open up more space in the main bunker for hotel rooms and residences. He adds that they are also considering another secure building for collector cars, motorcycles, and other valuable vehicles. With these features, The Diefenbaker is designed to serve as a private base for people, data, and valuables, as well as a hotel or residence.

Debert Airport is less than half a mile away, so residents with private planes can easily reach the property. For others, Halifax Stanfield International Airport is about a 50-minute drive. The location offers privacy but is still accessible from cities like Boston, New York, Toronto, and Montreal without complicated travel. The nearby former military airstrip is also important for emergency planning. Fitzthum says Bespoke is creating a subscription-based extraction service for owners and their families, using former military staff and private planes if regular travel becomes difficult. “We have standby time for less than 24 hours, and then we can go wherever they want,” he said. This service could also include private medical evacuation to a suitable hospital if a client becomes seriously ill while traveling.

According to the developers, the completed complex will be able to provide its own energy, water, and food for six to nine months. The plans feature a private solar grid, water purification on site, and underground food production. There will also be a second secure building to help with food production, so the kitchen can keep running even if deliveries are interrupted. Fitzthum explains that staff and security will have their own living spaces inside the bunker, which means the property could keep operating during a long lockdown.

The plan also includes medical facilities on site and areas where residents can have privacy if being confined becomes too stressful. These features are key selling points, but none have been fully tested yet. The bunker also has a spa and cigar lounge, giving it a hotel-like feel. Still, its success as a shelter will come down to the basics: steady power, clean water, good ventilation, and enough food.

In 1959, Prime Minister John Diefenbaker ordered the construction of emergency shelters as the risk of nuclear war grew. The Camp Debert bunker, finished in 1964, was one of six regional shelters built to protect government and military leaders. Its walls, a meter thick, could withstand a five-megaton nuclear blast from about two kilometers away. Filtration systems were installed to block chemical, biological, and radioactive contamination.

The building stored enough food and water for about 350 officials to live underground for up to 90 days. Their families were not allowed inside. The shelter’s purpose was to keep enough leaders safe so the government could keep running after an attack, rather than to protect the local community.

The bunker was taken out of service in the 1990s and later opened for tours before it became a secure data storage site. The current owner, Jonathan Baha'i, also used it for laser tag, esports events, and a Cold War-themed escape room. These activities stopped during the pandemic, and most of the property sat unused until plans for a hotel and residences came together.

The shelter has already proven helpful in a real emergency. When Hurricane Fiona hit Nova Scotia in 2022, Baha’i opened the shelter to coworkers and their families, offering heat, food, and power. While this situation was not the disaster the bunker was designed for, it showed how the building could help during a regional crisis.

Mansfield says more people are interested in fortified properties as buyers worry about extreme weather, international conflict, and other disruptions. Fitzthum adds that the potential buyers are more diverse than the developers expected. At first, they thought only wealthy people near Halifax, Boston, New York, Toronto, and Montreal would be interested. But now, inquiries have come from Europe and the Middle East, including families looking to buy several suites. “I spoke to several clients of mine globally, and a lot of them are super interested,” he told me.

He says the market is unusually mixed, with buyers ranging from young people with crypto wealth and inheritors to older families with established money. For many, the main draw is not about expecting a certain disaster, but about having a safe, staffed place to go if normal systems break down. The project offers this peace of mind to a small group of buyers who can afford both the suite and the high annual fee.

The Diefenbaker is designed to serve three purposes at once: it’s real estate, a boutique five-star hotel, and a fully functional survival shelter. When owners are away, the hotel keeps the suites in use. The residences generate capital and ongoing fees. The original bunker adds a unique history that sets this project apart from any new resort.

Most hotel guests rarely notice the walls around them. At The Diefenbaker, those strong, secure walls are the main feature. The spa, dining room, and custom suites help make the concept appealing. Still, what buyers truly get is the chance to stay safe during a crisis, behind doors that lock tight.
