japanese architect keiichi hayashi has sent us images of 'house in osaka', a three-storey
private house in a dense residential area of the city. featuring a home for a pet tortoise on
the roof, the design features an outdoor pond and tree which can be seen in the interior as
projections of steel cubes on the ceiling.

street view

situated on a narrow plot bound on three sides by neighbouring structures, the house takes advantage
of its only open face by concentrating the majority of their windows to face the street. small windows
for cross ventilation are placed strategically in order to avoid looking on to the windows of the adjacent
buildings. a roof light over the kitchen provides additional natural daylight for the communal space.

outdoor pond on the roof

in order to take total advantage of the site's area, the internal programs carry combined functions
to render each room as 'places': the children's bedroom are conjoined, being divided by a centrally
standing circulation unit housing the staircase. the sink of the washroom is placed off as a nook
from the study to minimize the presence of partitions.
