Starting off from selecting two formal logics images that communicate assembly, modeling logic and formal aesthetic in everyday lives, drawings of parameters that interpret the logics were followed by a hybrid drawing where languages of each drawing could be interlocked and blended together. Developing the hybrid drawing led to discovery of a new cloudlike figure with straight sides and an arc that tangents to them. The logic of making 3d from 2d was slanted extrusion of the figure that could show tangent edges along the slope and the extrusions with different sizes and were overlapped and blended together like a lot of ornaments in the rococo period were hard to be distinguished by its own shape from a distance. From several experiments of massing ideas, the figures that consist of arcs and lines were arranged having different degree of tightness, which led to different scale of openings, courtyards, and outdoor hallways between the figures. The cloudlike parameters with arcs and lines could be found vertically as well as horizontally and the vertically and horizontally projected parameters became openings, voids, windows, and space.  The ground also has the same formal logic as buildings of arcs and lines which are the extension of existing buildings' parameters. To make main entries of north-south direction, the ground with ground level is open to north streetside and south parkside, and levels of other pieces of the ground get higher. Along with the main flow of human traffic of ground level, circulations with outdoor courtyards, hallways and stairs are spreading out to interior spaces of the buildings.
