Oppidum: Meet builders of luxury underground bunkers utilising advance tech
“We are an engineering, technology and development company specialising in ultra-luxury fortified underground residences. We create spaces that are totally secure and utterly discreet yet sumptuously appointed and entirely bespoke – all underground, within your own domain.” That is how Oppidum introduce their works.
To put it in easy-to-get way, below is a listicle of what they do:
• OPPIDUM: a Swiss-based company, specialized in designing and constructing luxury underground bunker structures, utilizing advanced technology expertise.

• New concept of bespoke luxury underground bunker solutions at clients’ existing estates.
• Private art gallery, secure garage, discreet meeting spaces for business and leisure, including a spa and an indoor garden.
• Optimised for super-luxury everyday lifestyle, while prepared for all surface threats.
• Independent off-grid operation (power systems, water, supplies).
• Suitable for short- and long-term contingency, private business or leisure use.
• Three luxurious models to get inspired: L’Heritage, Linear, and Futurist.
• Designed up to the highest levels of NATO STANAG 2280:2016 military standards.
• Protected by complex integrated security systems.
• Commissioning and build processes undertaken in full compliance with all relevant international and domestic laws, following rigorous due diligence.
OPPIDUM offers three luxurious underground living models to choose from: L’Heritage, Linear, and Futurist.
All three models offer private art galleries, secure garages, discreet meeting spaces, spas, and indoor gardens, as well as being optimised for everyday luxury living and prepared for all surface threats.
But L’Heritage is a classic, timeless design, inspired by the ancient Roman fortresses known as oppida. It features elegant, old-world charm and all the modern amenities and security features you would expect in an Oppidum underground living space.
It offers a total of 1,000 square metres of accommodation, comprising generously proportioned public and private areas, an indoor garden, gallery and technical spaces – all hidden deep beneath the ground.
Generally speaking…
Let’s see what sustains life underground at Oppidum.
Technical rooms and equipment
The hidden technology that sustains life underground is housed in a suite of technical rooms.
The principal systems operate completely autonomously, requiring no human intervention, with backup circuits that deploy instantly.
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.
Oppidum is fully airtight and gastight and can be completely isolated from the outside atmosphere if required. A unique high-pressure air reserve and internal circulation enables occupants to breathe normally and safely.
The air filtration unit is equipped with a CO2 removal system; combined with an auxiliary oxygen supply. That provides breathable air when there is insufficient or no fresh air entering the building.
Water
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.
Applying thinking and technology from NASA, the storerooms contain stocks of long-lasting and highly nutritious food, sufficient for months or even years; the separate medical room has its own secure storage for essential medical supplies.
Construction
Local geological and hydrological conditions have a major impact on each Oppidum’s design and construction, so multiple surveys are conducted in the project’s early stages. Using advanced simulation software, an Oppidum can be designed up to the highest level of NATO STANAG 2280:2016 standards.
The construction generally comprises an open excavation with a temporary retaining structure at the perimeter. The primary excavations can extend 15 metres below ground level and involve displacing up to 45,000 cubic metres (60-70,000 tonnes) of soil.
The main structure is a reinforced concrete shell designed to withstand both static and dynamic loads, such as blast and shock waves and natural seismic activity. An Oppidum is constructed using high-density concrete with magnetite-based aggregate – the same formulation used to build nuclear power plants.
