Although this house was designed for a flooding site, it could handle most tsunamis with its rigidity and steel clad paneled underbelly at a high stance. For the much less probable tsunamis that could rise above the door sills and create massive amounts of floating debris, we suggest soluble bolt anchors on top of each column. This way the house will float as a rigid unit capable of taking a lot of hits and yet remain safe. Of course a solid chain would tether it to a reliable point on the ground. This is not a compromise as both safety and practicality are maintained in a relatively low-cost house.
