We sell 12-foot-wide DIY tunnel shelters and Quonset hut kits nationwide, with local build help in the Pacific Northwest. Both are hillside preparedness shelters. The Viking Shelter is 12 feet wide (12 × 40 is the usual size; smaller or larger is fine). A Quonset hut is wider.
New here? Design a shelter in 3D first, then tell us about your land and your project. The 3D builder and SteelX calculator give rough estimates only. They show how a Viking Shelter goes together and roughly what it takes, not an exact quote or engineered plan. The form takes about 10 minutes.
Filling out the questionnaire
Tap a white box to type in it. Tap a choice to pick it. Picked choices turn orange.
Questions marked (required) must be filled in. Skip anything you are not sure about.
When you are done, tap Send my project at the bottom. We reply within 2 business days.
Tip: These 3D models work best on a desktop or laptop computer, with a bigger screen and a mouse. They still work on your phone.
Pick your shelter type
Choose one to start. You can switch any time. This 3D model is here so you can see how we work and roughly what a shelter takes.
Rough estimates only. This 3D model shows how a Viking Shelter goes together and roughly what it takes. It is not an exact quote or engineered plan. Final numbers come after a site review and engineering. Contact us for pricing.
SteelX calculator (rough estimate)
Type in your cubic yards. We figure a rough estimate of the pounds and boxes of SteelX micro-rebar.
Rough estimates only. This 3D model shows how a Viking Shelter goes together and roughly what it takes. It is not an exact quote or engineered plan. Final numbers come after a site review and engineering. Contact us for pricing. SteelX dose. Shotcrete: 1 box (22.5 lb) per cubic yard. Foundation: 11 lb per cubic yard (a conservative estimate, pending final engineering review). No waste factor added.
No design yet — that’s fine.
You can still fill out the questionnaire, or go back up and design a shelter first. If you do pick a size in 3D, it will show up here so you can match it on the Size question below. Figures in the 3D builder are rough estimates, not an exact quote.
Start Here: Tell Us About Your Project
Every build starts with the land and the person behind it. The more you tell us, the more honest and useful our answer will be. Takes about 10 minutes.
