It's a work on how to interpret the properties of crack. and it has a meaning on searching the way of principle creating cracks. so finally it is trying to achieve the spatial qualities of cracks like unexpected diversity, ambiguous and dynamic into architectural design. they can be emerged in the process of transformation like being cut, rotate, shift and delete. so what I focused in design process is to expect same qualities in the building by using same transformation. and there is also meaning to experiment how to develop that qualities as architectural space.
