'47% house' by tokyo-based practice kochi architect's studio (kazuyasu kochi) is a two-storey
private dwelling in kamakura, japan. providing a number of generously-sized outdoor programs,
the interior floor area equals 47% of the total building footprint to result in a holistic layout that
incorporates exterior spaces into its design.

starting from a simple box form, the necessary programs were arranged then carved out to
incorporate a small garden, outdoor terrace, and an elevated entrance hall that opens up
to the outdoors. an outdoor staircase provides access to the house, which accommodates its
communal space - living, dining, kitchen - on the second level. the roof was pulled up to
an asymmetrically-pitched form, lending the house a playful exterior profile.

from the outside, the house is read to consist of a dark shell that partially wraps around
a white volume. the structure extends out to provide shade to the entrance hall and generous
outdoor terrace. as a result, the line between the interior and exterior is blurred. floor-to-ceiling
glazing which lines both sides of the second storey adds to this effect, engaging the living space
in direct dialogue with the site.
