Take a look inside the luxury bunkers being built under the elite’s mansions

‘Our vision at Oppidum is to build the world’s most beautiful and secure contemporary fortified residences,’ Jakub Zamrazil, Oppidum founder and chief executive officer, explained.

‘They are places of serenity and absolute safety for owners and their families.

‘We are privileged to offer our clients the highest levels of service, creating beautiful places that will protect them, and their legacy, for generations to come.’

Jakub said that Oppidum takes an ‘optimistic view’ of the world, but believes it’s ‘wise’ to be prepared for unforeseeable and unpreventable events. 

‘In an uncertain world, an Oppidum provides peace of mind,’ he said. 

‘It is a place of strength that enables our clients to preserve and protect what matters most.’

The main features of the bunker include NASA-level technology which allows stocks of nutritious food to be stored for months or even years, an inner garden, a medical room, high ceilings and opulent custom-made furniture.

According to Oppidum, access to the spacious underground garage, known as the Parc Fermé and guarded by an internal security gate, is via a hydraulically actuated ramp set into the ground so as to be almost invisible.

The secret gallery is extremely secure, meeting the strictest insurance company criteria.

In the ‘inner garden,’ flowers and plants are sustained by sophisticated automatic irrigation.

Through full-light spectrum simulation, the sun rises and sets and the seasons change in the skylight overhead.

Bunkers also include swimming pools as well as exercise machines and equipment.

An Oppidum has two independent air filtration units. The primary unit is designed for ordinary peacetime use. The secondary unit is a military grade chemical, biological, radiological and nuclear (CBRN) system.

An Oppidum is fully airtight and gastight and can be completely isolated from the outside atmosphere if required.

Bunkers feature two independent air filtration units, an ordinary one and a military grade one, both of which are equipped with a CO2 removal system and an auxiliary oxygen supply that provides breathable air when there is insufficient or no fresh air entering the building.

Water is supplied from deep underground by a private well, entirely independent of the public supply.

In case of a power outage, blackout or instability in the grid, the power system seamlessly switches to one of its multiple fail-safe alternative power sources, including twin diesel generators and back-up batteries.

Marc Prigent, principal architect and designer of Oppidum L’héritage, added that Oppidum is an ‘extraordinary technical and professional challenge, entirely beyond any brief we have previously received for a secure space.’

He said: ‘Every project is conceived, designed and realised without compromise to be worthy of our clients, the most powerful individuals in the world.
