A tornado resistant dome house. The shape of the dome house is a spheroid section, and is given by a formula. The dome house shell is made up of a plurality of tiles formed to conform to the shape of the dome house. The tiles are mutually connected by means of horizontally and vertically disposed elongate members extending through lumens in adjacent tiles. The tiles are also attached to a dome house foundation. The curved, low-profile shape of the house, combined with the mutual attachment of the tiles, and their attachment to the dome house foundation, improves the resistance of the dome house to high winds associated with tornadoes and hurricanes. Adjacent tiles are cushioned by springs, and are maintained in position relative to each other by means of a tongue-in-groove attachment between adjacent tiles.
