This is two-story house for my clients in dense residential area in Saitama, Japan. Because the owned property is bordering two heavy traffic roads, it was required to sound suppression because there are always many cars and pedestrians. My client requested to have the house that does not expose living condition to outside and has an open air to inner space universally. To utilize Light Court, they can feel fresh sunlight and gentle wind in their house. At that same time, for the prevention from the sound and protect privacy inside, we utilize the half mirror glasses for the skin of the house.
