We propose a floatable flood-resistant house that is resistant to flooding up to a depth of 5 m. It includes foundation, water supply and drainage pipes that enable smooth ascent, and mooring devices that prevent the loss of the house and slippage during landing. We also propose a draft calculation method to check the ascent balance. These measures and calculation methods were demonstrated in the inundation test of the full-scale test building. It was shown that it is possible to remove foreign drifting objects under the house after landing and to pull it back to its original position.
