About Two Sails Casa

Two Sails és una casa vora el mar dissenyada per a una família de dues generacions. L'edifici de fusta de dues plantes es troba a Okayama, Japó, amb una superfície construïda de 250 metres quadrats sobre una parcel·la de 800 metres quadrats. La forma de la coberta recorda la vela d'un vaixell i ajuda a introduir llum natural i brises marines a l'interior. Els espais habitables estan dividits en zones nord i sud, de manera que cada generació manté la seva pròpia privadesa. Un passadís cobert connecta les dues zones i permet desplaçar-s'hi fins i tot els dies de pluja. Les parets exteriors estan revestides amb metall durador que resisteix la corrosió de l'aire marí.
