Was away for a day , jusr got back

What i had thought of was from what Inca asked
May be this buildings will overhang from the heavy branches of the giant swamp trees like a strange fruits,
This made me imagine the hut having a hook or a loop at the peak of the roof that can be attached to a large limb of a swamp tree. When the tide starts to rise, either the owner un-ties it or the rising water will lift the hook off the limb.
Once the water returns to its lower level, the owner will re-tie it, or it must be in its place when the water levels go down, so the hook will drop on the limb.
I hope this is clearer, if not let me know and i will try

to draw a pic.
