Most useful material properties for building tsunami-resistant submersible buildings? (Magical material engineering)

My magic system transfers quantities of certain properties from one object to another. For instance, electrical conductivity from metal to rubber -- the metal becomes less conductive, and the rubber becomes more conductive.

To transfer properties, you need special equipment and fuel proportional to the quantity to be transferred. The fuel is decently difficult to create.

There would be a point of diminishing returns, after which exponentially more of a property must be taken from one material to give a lesser amount of the property to the other material.

The magic has only been known for 50-ish years, and is a well-kept secret of a particular tribal people living on a coastline. They have access to native metals, and have been learning to mine and refine metals for the past 30-ish years, and can make steel with difficulty. They can make glass. They do not know how to make gunpowder.

The coast they are living on is a fault coastline, similar to Chile, but the world also has extreme tides and regularly occurring tsunami, such that there is not much sand or dirt along the coast. The tribe lives there because of political force, spiritual connections to the land, and to create the fuel for the magic (the ingredients for which can only be found on the coast)

Current ideas for transferable properties:

• Electrical conductivity
• Thermal conductivity
• Specific heat
• Boiling point
• Melting point
• Freezing point
• Ductility
• Malleability
• Hardness
• Tensile strength
• Color
• Transparency
• Density
• Elasticity
• Resistance to corrosion
• Flammability (Ignition temperature)
• Friction
• Magnetism

Which 7 properties are best for creating tsunami-resistant buildings which can be submerged for extended periods?

The general design for buildings would be dome-like, since I understand that spheres and cylinders tend to resist tsunami more effectively than cubes.

(If a material property not listed here occurs to you and would be very useful, it would be much appreciated. Otherwise, only consider the properties listed.)
