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.
