in the manicured greenery of a recently consolidated municipality in the kagoshima prefecture, matsuyama architect and associate’s ‘house in aira’ employs rounded volumes to move light around the quiet spaces. while exteriors are crisply orthogonal and clad in panels of dark wood dotted with the white knots and burls of the grain, the interiors are almost retrograde with their unfailingly filleted vertices. the effect is the spill of light that enters the hallways, despite their narrowness, as well as a maze-like space that the client’s children can safely play in. buffered concrete floors complete the monochrome palette while ceilings and aperture-ridden walls display a skin of directionally-grained wooden square panels.
