<p>Opposite edges of a plurality of dome pieces (10-19) constituted of styrene foam are joined and bonded to one another to form thereinside a semispherical living space (SP). The bases (DB) of the dome pieces (10-19) are locked to the foundation (PD) so as to restrict the upward movement of the plurality of dome pieces (10-19), and a restricting unit (SM) is provided along the outer peripheries of the dome pieces (10-19) so as to restrict the outer-peripheral-direction movement of the dome pieces (10-19). The dome pieces (10-19) are formed of styrene foam having an expansion ratio of 20 times and a thickness of 20 cm, are coated on the outer and inner surfaces thereof with resin concrete after fabricated into a semispherical form, and then are coated with a weather-proof, fire-proof paint.</p> |
