the project led by architect ryutaro saito of DOG was realized for a young couple who wanted a single home catering to their daily needs and motorcycling hobby. due to the strict restrictions of the site which was to not touch the existing stone walls and this limited the design possibilities. the resulting scheme sees the double roof hiding the visibility of two floors. the ceilings follow the incline of the roof and a consecutive ceiling appears in the room and links an interior and an exterior design. on the second level, the smaller roof is lifed to form a clerestory window and illuminating the upper level while retaining privacy. in the middle of the volume, the roof is interrupted by an opening to enable a tree and small courtyard to be formed.

the facade is defined by the old and new, the old being the stone walls and the new being the roofs

a small window has been incorporated in furniture

the second level sits above the kitchen as a half-mezzanine level

the space follows the slant of the ceiling and the clarestory window

the large ceiling overlaps the 1st floor from the 2nd floor

the interior has been planned around this roof forming various spaces

a clear relation has been established between the motorcycle garage and the living space
