Yeah. If we can. Might be safer and more efficient than a wall, in the long run. Building anything right on the beach is tricky, but if we start as far back as we can...

And if we can get the right kind of materials. Maybe an outer layer, a few pillars and support beams across the middle, then lay the floor boards down on top of that. The rest of it doesn't have to be anything fancy. Thatched roofs. Maybe more than one structure with simple bridges between them, your standard rope ladders to get up and down...
