About Two Sails Hûs

Two Sails is in hûs oan see, ûntwurpen foar in famylje fan twa generaasjes. It houten gebou fan twa ferdjippings stiet yn Okayama, Japan, mei in bebouwd oerflak fan 250 kante meter op in perseel fan 800 kante meter. De foarm fan it dak docht tinken oan in skipsseil en helpt om natuerlik ljocht en seewyn nei binnen te heljen. De wenromten binne ferdield yn in noardlike en in súdlike sône, sadat elke generaasje syn eigen privacy hâldt. In oerdekte gong ferbynt de twa sônes en makket ferpleatsing mooglik, sels op reindagen. De bûtenmuorren binne beklaaid mei duorsum metaal dat bestân is tsjin korroazje troch seelucht.
