Needless to say, I would to tell what I heard before regarding contemporary experimental design for building. As a matter of fact, the owner of this underground building is a professional instead of architecture. The purpose of this building is to create structure that environmentally friendly for people in the immediate surroundings. Based on the owner' experience, he is less likely to dwell in urban area, thus, he decides to build this extremely marvelous installation using double layer strong glass to catch energy from the sun in the rural area. What interesting from this building is that using plenty of window and mirror to have enough light. Subsequently, this building also can reduce carbon dioxide which is perilous to occupants.
