In Japanese, Fujitsobo means barnacle. The word is implemented by the Japanese architects Archivision Hirotani Studio on this Fujitsobo house, cladded with copper in a barnacle pattern.
The house incorporated skylights mounted in three pitched volumes on the roof. These funnel light down into the house interior where it penetrates to the storeys below due to slit-like glass panels in each floor. The copper sheets that cover the roof and walls will change appearance over time.
