We discuss an evaluation method of architectural space. In the discussion, we propose several kinds of procedure to understand architectural space. The most basic way is to watch the physical boundary of space which relate to various characteristics of architectural space. Through this idea we can caluculate the numerical value for architectural planning. We have already analyzed several cases of space in this way and published two academic papers. In this time, some kinds of space boundary are automatically organized, evaluated through a certain procedure of GA and evoluted to the better space. Our trial was successufully conducted.
