Located in southern Osaka, the site for this house is located on the intact slope of an old hillock,
facing a prefectural road built some 40 years ago that cuts through it.
The site, which features a sloping embankment to the south, commands a clear, unbroken view of
a row of cherry trees on the other side of the road. It also boasts a superb view of a beautiful
plum grove located just above these cherry trees. We embarked on the design for this house in
an attempt to take full advantage of this picturesque view.
The building consists of a two-layered structure leading from the road to the north, where the
approach to the house is located. Upon entering, the house takes on a triple-layered structure
and layout, inclusive of a basement level located on the south-facing side next to the slope. This
basement houses a bedroom, while the entrance hall, bathroom and Japanese-style guest room
are located on the first storey. The living room, which is the centerpiece of the house, is located
on the second floor along with the children’s room. Because this was a small house, the focus of
the design was on how we could ensure a continuous flow and sense of connection across these
The basic structure of the house was built out of reinforced concrete. The only portion of the
building that featured wooden construction was the roof, which spanned a length of 5.3m. In light
of this, we decided to adopt a box-beam structure that was constructed out of right-angled
section components with a small diameter and plywood boards, rather than wide sectional beams.
In addition, slit-shaped skylights were installed in between the box beams in the ceiling, allowing
even, uniform light to illuminate the long expanse of the house that stretches from north to south.
The crevasse-shaped voids that connect the three levels of the house to each other, along with
the staircase that runs parallel to them, create a sense of flow and continuity across the entire
space, in addition to dispersing sunlight that enters from the overhead skylights all throughout
the house until the basement level.
