Know Your Shelter's Air Is Moving Before You Shut The Hatch

Weekly buildable plans for the shelter you dig yourself: airflow that actually moves, drainage, and a soil test you can run on your own ground in an afternoon.

What lands in your inbox

Built to use this week, not to file away.

1 Airflow You Can Prove

2 Test Your Own Ground

Hard rock, high water table, or hillside: find out before the first shovel.

3 Ask The County Right

How to ask which classification your dome fits, instead of leaving without an answer.

Don't Suffocate In Your Bunker

Warm air rises and leaves, so cool air has to be drawn in at floor level. We walk the intake, the outlet, and a candle check you can run before your family ever goes down.

The rest — the part that makes it click — is for members.
Why it's worth $9.90/mo

One good week pays for a month. This saves you many.

You're not paying for 'content' (that's everywhere and half-wrong). You're paying for the tested way, the exact steps, every week — and for a real answer when you get stuck.

“I had the airflow backwards in my head, figured the intake belonged up top. The weekly letter laid out why the cool air comes in low at the floor, and I redrew my vent runs that same evening.”

Earl R. · 71 · Ohio

“Damp was my worry more than anything. Between the moisture notes and the airflow section, I finally understand why the air down there sat so still and smelled the way it did, and what to change first.”

Margaret T. · 66 · Queensland

Fair questions
I hit solid rock a few feet down. Can I still build a dome shelter?

Often yes, as a bermed build rather than a buried one. The weekly letter covers berming over rock, drainage below the shell, and keeping the air path working when you cannot go deep.

Do the plans assume I have a crew and heavy equipment?

No. Measurements, mixes, and work order are written for one owner with hand tools and a helper, plus notes on where renting a machine for a weekend actually pays off.

Isn't this on the internet for free?

Bits of it, scattered and half-wrong. Here it's tested, start to finish, with the exact steps — and a fresh one every week.

I'm not as young as I was — is it hard?

No. Plain steps, big print, one a week. Nothing fancy, the way it's always been done.
