japanese architects ON design partners (osamu nishida, takanori ineyama, rie yanai) have completed
'house with eaves and an attic', a three-level dwelling on a hilly site in in tokyo, japan. standing slim and tall,
the design features an exaggerated pitched roof that is translated to the form of the interior space.

located within a cluster of trees on the edge of a cliff, the house is built on the only flat part of the site
which measures approximately 4.5 m by 16 m. the design leaves the trees untouched and even
incorporates their presence into the structure by letting them grow through the over-extruded roof form.
singular and solid, the roof is clad in a 'doll house'-like fashion with grey shingles. puncturing the surface
interspersedly are a series of picture windows of different sizes which lend the house a playful identity.
the extended eaves provides shade as well as controls views from the exterior.

accommodating extra vertical space, the 'attic' level hosts the main communal programs such as
the kitchen and living room. the windows provide views of the trees, inviting the elements of
the outside inwards. in a similar manner, the ground floor opens up to the cliff side of the site
with floor-to-ceiling glazing. the middle level is kept windowless and provides a generous amount
of space for storage.
