This is the project for a residence on the mountain slope with incredible ocean views including the view of Mt. Fuji. According to the site condition, each floor is designed differently. The 1st floor has minimum floor area with de-formed concrete columns to create diagonal movement for enjoying outside activities, the 2nd floor has simple bedrooms like concrete shells and the 3rd floor has maximum floor area by cantilever with light weight wooden structure. Then the 3rd floor has a panoramic ocean view living with full open sash to connect terrace and indoor spaces as one big space.
