From the architect. Casa Wakasa, home to a young family of four is located in the suburbs of Osaka, Japan. The house attempts to be both a reflection into contemporary Japan's family life (sense of family vs. privacy) as well as a solution to balance individual freedom and space with collective activities and time.

The basic unit of the house is an amalgam of a room and an outdoor courtyard; each room for each member of the family has an integrated garden as its counterpart.

The house design gives emphasis and space to the glass-sided living room, surrounded by open gardens. The father who works as a dentist from 9AM to 9PM everyday wants to have a place in his own house that at the end of the day he could withdraw even from his family, his wife and two young daughters, to pursue the subjects of his personal interest - music, films and books. This open glass room, connecting to the house only through an underground corridor, is the sanctuary where he can be himself. The family has meals and activities together in the family living and dining room but each one of them could withdraw into their own world in their own room / garden.

The spine promenade / passage linking all the rooms is designed as an "engawa", the semi-outdoor transitional space seen in traditional Japanese architecture. This implies its ambiguous and transitional essence; it is not a room yet functions as one, not merely a corridor but used as linkage. Like traditional "engawa", it is the true linkage in many senses; it links the indoor rooms with outdoor gardens, links spaces together into a composition, and it links multiple individual worlds into a family.

I love how they made the entrance to the house indirect, obviously inspired by Ando's principles both in planning and composition. The difference I think is that they paid a little more attention on the structure's formal or visual qualities. It is more visually appealing but more visual focused as well reducing the capacity of the structure to emphasize the other senses. Nonetheless, beautiful house, minimal yet rich in experiential qualities.

Climate. Subtropical climate make it unnecessary to think about such things. I know what kind of technical difficulties it means to build a concrete building in nordic climate but there are beautiful examples in Switzerland, in "Passivhaus" standard as well.

obvious thermal bridging is not an issue in Japan... how do they get away with it?

Wow, this is beautiful. It looks great lit up at night, and the interior manages to be fairly warm in spite of the concrete and steel.
