The Design

About Two Sails Haus

Two Sails ass en Haus um Mier, dat fir eng Famill mat zwou Generatioune entworf gouf. Dat zweestäckegt Holzgebai steet zu Okayama, Japan, mat enger Bauflëss vun 250 Quadratmeter op engem Terrain vun 800 Quadratmeter. D'Form vum Daach erënnert un e Schëffssegel an hëlleft, natierlecht Liicht a Mieresbrise an den Interieur ze zéien. D'Wunnraim sinn an eng nërdlech an eng südlech Zon opgedeelt, sou datt all Generatioun hir eege Privatsphär behält. En iwwerdaachte Corridor verbënnt déi zwou Zonen an erlaabt d'Beweegung och u Reendeeg. D'Aussewänn si mat dauerhaftem Metall verkleet, dat der Korrosioun duerch d'Mieresloft widersteet.
