But as the common garden directly faces to a street on the south, making windows on the same side was not good to keep privacy of the family. Generally in this case, building a wall between the street and shutting the curtain could be a stereo-typed solution in Japan, but we didn�ft think it�fs clear way to solve the problem. So we introduced a private terrace on the flat roof of the garage, and connected it with the common garden through a slope. Thanks to this difference in height connected by the slope, the private terrace is protected from passers-by�fs eyes, though it is opened to the garden and the parents�f house. The living room and kitchen are on the second floor and opened directly to this private terrace, which helps getting sunlight and fresh air with privacy.
