The site is
plentiful environment with greens, but the all the site of around 600 square
meters with an inclination of 30 degrees.
The extensive
site is also surrounded by rich nature. Next to the site is a forest of bird sanctuary,
and there is mountain range in a view from the site.
Our main
focus for the planning was to create a close relation between the extensive
inclined land, environment, and the residence.
It’s very
important that the floor touches the ground to create the close relation between
the inclined land and the residence, and to connect the inclined land and interior
space.
We create the
foundation which is also retaining walls against the earth as living space to form
a horizontal surface which connect the inclined land. By designing the first
floor as a floating volume in the air we suggested an open living space on the
ground floor surrounded by the foundadtion and the volume above.
The foundation
the inclined land is LDK, and the floating volume is private room and bathroom.

The
foundation is following a site and its circumference visually 360 degrees along
the inclination of the site, it’s also connect upper and down part of the
inclination land as a circulation
The volume,
which is lifted up to upper level of the foundation, is constructed by timber
structure for both cost control and reducing weight. We designed the volume as
a one-room, and it is possible to divide by sliding doors and movable closets
for the change of family make-up
The windows
in this floor are cut off the surrounding landscape as picture window, and it’s
different from the window in the ground floor, which follow surroundings
visually.
By designing
the foundation and retaining walls against the earth as living space the small
low cost residence realized which connect the extensive inclined land and
environment.
