CUBE Bunker,
answered.

A bunker built from steel cubes that are 10 by 10 feet outside. Each cube is fabricated in Utah, delivered to your land, set in an excavation by crane and joined to the next one with a bolted, gasketed mate package, so two to eight cubes become one sealed space.

Styrkholm LLC of West Point, Utah, designs, engineers and fabricates every cube. CUBE Bunker dealers sell and install them in their own areas. In Utah, Styrkholm installs directly.

Complete bunkers with the required air, power, heat, plumbing and waste systems start at $251,900 for the Holm 2 and run to $766,800 for the Holm 8. Those are Styrkholm installed prices in northern Utah. Outside Utah, your dealer quotes freight and installation for your site.

Each cube is 10 feet wide, so it travels on a flatbed as an oversize load with state permits, and in most states with signs and flags rather than escorts. A crane sets each cube in the excavation.

Yes. Any outside wall that has an end cap can take a new cube. The end cap comes off, a mate package goes on, and the new cube opens into the old one.

In the 3D Builder you drag a room onto the model: entry, decontamination, utility, communications, kitchen, dining, living, gym, bunks, bedroom, bath, medical, food and water, storage or workshop. The Builder places the door, the emergency exit, the mate kits and the end caps for you.

CUBE Bunker dealers are being appointed state by state. Until one is in your area, Styrkholm handles your project directly. Tell us where you are on the Find a Dealer page and we will put you in touch.

Plan for the long days: exercise gear, books, games and puzzles, music, a record player, AM/FM and weather radios, movies downloaded to a drive, extended prescriptions and a plan for anxiety. Add a gym cube in the Builder for mats and weights. Styrkholm keeps the full printable checklist at styrkholm.com/resources/what-to-stock-in-a-bunker-besides-food.

No. Cube prices are preliminary while engineering for the cube system is completed. Your final price is confirmed in writing after a site visit, because soil, depth, water table and access change the work.
