A low-cost hurricane and earthquake resistant house structure includes a rounded shape external wall constructed of a plurality of circumferentially adjacent wall segments, each secured to an adjacent structural vertical stud secured to the ground via a shock absorber. Each wall segment includes a plurality of blocks located and secured on top of one another. A foundation groove receives at least a portion of a lowest block of each wall segment therein, and spaced from inside foundation walls. An aerodynamic roof is secured to the vertical studs, and a floor is mounted on shock absorbers on the ground and connected to the wall with a flexible material.
