The Design

About Two Sails Casa

Two Sails é unha casa á beira do mar deseñada para unha familia de dúas xeracións. O edificio de madeira de dous andares está situado en Okayama, Xapón, cunha superficie construída de 250 metros cadrados nunha parcela de 800 metros cadrados. A forma da cuberta lembra a vela dun barco e axuda a atraer a luz natural e as brisas mariñas cara ao interior. Os espazos habitables divídense en zonas norte e sur, de xeito que cada xeración conserva a súa propia privacidade. Un corredor cuberto une as dúas zonas e permite o desprazamento mesmo nos días de chuvia. As paredes exteriores están revestidas cun metal duradeiro que resiste a corrosión do aire mariño.
