When the world is over, Oppidum is ensuring your standard of living continues. The L'Heritage Underground Homes offer the uber-wealthy luxury digs in the post-apocalypse. Designed by French architect Marc Prigent, the lavish bunkers feature a 10,000-square-foot interior decked out in bespoke furnishings and include spacious suites, indoor pools, lounges, gardens, and even art galleries. With zombies and looters running rampant, security is key. That's why each one is protected by fortified blast doors, military-grade security systems with facial recognition, and off-grid systems.
