• A design concept for a subterranean doomsday shelter is reimagining the future of apocalypse-proof living.
• Called "Underground House Plan B," the flying-saucer-shaped bunker combines high-security systems like a fireproof evacuation ring with the comforts of a modern, above-ground home.
• Plan B uses LED lights, image projections, and greenery to make the residents feel as if they could step outside.
• Plan B is the brainchild of Kyiv-based Sergey Makhno Architects and was designed to comfortably fit two to three families plus staff.

Once inside, residents will be fully protected from outside disasters thanks to a closed ventilation system, medical treatment room, and fire-resistant evacuation ring accessible from almost anywhere in the home.

From there, spiral staircases and an elevator lead to the living space 50 feet below ground.

In lieu of windows, the bunker uses LED lights to mimic sunlight. It also incorporates materials like stone and wood to evoke the outside world.

Through these design elements, Sergey Makhno Architects wants "to create the illusion of being above the surface — as if you could look out the window and see the blue sky," the studio said.

As is, Plan B can accommodate two to three families with children, plus staff and their children, though the design could be adapted to accommodate more people.
