Keep it simple and functional. Dig a shallow trench around the crew area, line it with a thick timber frame and then cover it with a mix of earth and layered stones for weight. Reinforce the front with a 12‑inch thick stone wall and add a small, removable steel gate for entry. Leave a narrow, angled opening on the side for a wind‑driven chimney that vents smoke and keeps the air fresh. Add a hidden trapdoor in the floor that opens to a storage chamber for supplies. Build a small, raised platform inside for sleeping, so you’re above any floodwater. Finish the roof with overlapping cedar planks, fastened with iron nails, and seal seams with pitch. That’s weatherproof, stealthy, and won’t scream at the storm.

Got it, keep the timber seasoned and the stone compacted, and I’ll slot a steel latch in the gate so it won’t give way. I’ll rig a test flame on the chimney, check the draft, and make sure the trapdoor slides cleanly with a weighted pull. We’ll have a reliable shelter and a quick escape route if the storm turns the tide. Let's get to work.

Alright, we’ll get the trenches in and the stone wall up before the rain starts. I’ll keep my eye on the seals, and we’ll have a fortress that doesn’t crack under pressure. Let's do it.
