Koya No Sumika is an extension to a traditional home in Yaizu, Japan. The extension was designed for a young couple by mA-style Architects. The Japanese firm came up with a modern design with space saving solutions. The result is a refreshing juxtaposition to the traditional architecture of the original home.

The exterior is a balance between white cement board and natural wood. The mix of crisp white and warm wood continues on the interior. The lofted ceiling features triangles of unfinished wood. White walls frame the lower portion of the home, sprinkled on both sides with built-in furniture. The decor is bare, just a few plants and lightbulbs strung from the ceilings. A simple courtyard garden adds a touch of green and connects the expansion with the original building.

Koya No Sumika is a gorgeous structure inside and out. The materials are arranged so as to add character to the space, without losing its minimal appeal. Overall, this is a charming home expansion that the residents will enjoy for years to come.
