Though currently just a concept, Ukraine-based studio Sergey Makhno Architects will work with contractors to develop systems in detail if the design enters the project phase.

Called “Underground House Plan B,” the autonomous concrete bunker is shaped like a flying saucer and comes with a rooftop helipad.

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.

To enter the bunker, residents must first pass through a disinfection shield.

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.
