japanese architectural practice katsutoshi sasaki have recently completed 'oshikamo house', a single family residence amidst
the residential neighborhood of toyota, aichi, japan. the footprint of the structure creates a series of open wings on either half
of the dwelling generating a unified interior to foster continuous interaction between the family members. vertically striated
white metal panels clad the changing volume shape, shifting from rectilinear outer corners to a concave niche, discreetly presenting
the main entrance in the front elevation and a tree in the rear of the home.

the unique spatial arrangement places the kitchen in the center introducing dynamic activity into the heart of the home
while the private areas of bedrooms and study rooms gradually transition into bisected corridors creating minimal opportunities
for extended isolation. the programmatic distribution compels inhabitants to cross through the communal area and then branch
into the gently curved passages with stairs and ladders to raised spaces to block direct views.
