japanese practice akio kamiya architect & associates has shared with us images of
‘house in tanimannari’, a two-part renovation project for a young couple in okayama, japan.
consisting of a two-storey detached room and a free-standing green house, the design maintains
a careful balance between the old and the new, being sensitive to the pre-existing main building
while injecting a modern character through materiality and form.

located west of the main house beyond a parallel-running retaining wall, the greenhouse
provides a place to cultivate local muscat grapes. the simple, square-shaped plan is pulled up
to a symmetrically-sloping roof form that moulds the space within into a triangular volume.
completely transparent save for the stacked stone base, the atmosphere of the interior shifts
according to the trajectory of the day; natural daylight filters in through the grapevines and
surrounding trees, resulting in a porously shaded space. newly paved with white brick,
the greenhouse retains thermal heat during the winter.

a former annex that housed two japanese-style rooms and a small storeroom, the detached room
utilizes the original structure of the building, maintain the rich identity of the exterior intact.
the ground level accommodates an open dining and living space that features a kitchen at
the center of its layout. a staircase at the back leads up to a bedroom that overlooks the area
below through a set of sliding screens.
