The purpose of this article is to investigate the forms and styles of pond at private housing in terms of diachronically influencing characteristics in the Choson Dynasty. From various literatures and records, we have selected 73 cases of pond. We have analyzed the types of pond based on square type, squared type with islets, and modified types and found the following results: 1) Chronically, shapes of pond had been chanced from the three prototypes into their features of deducting side or edge, adding a triangular or trapezoid shape, and installing more islets, and replaced their figures with gradually progressive from side having a straight lined shape to a curved one. 2) As for characteristics of arranging ponds, we found three patterns of arrangement - the juxtaposition with a similar shape of pond, juxtaposition with a different shape of pond, and the juxtaposition with a pond having different topological level in the light of the relation with a stream and a pond. We can conclude the two changed patterns of ponds at private residence in Choson Dynasty that the one had been transformed shapes of pond with sides of pond, and the others had been transformed juxtaposition with either a stream or a natural stream. From this research we can find an important implications in understanding patterns and types of garden in the Choson Dynasty from exploratory approach and in the future the relationship between topographical characteristics of private residence and Confucian ideas, and shapes of pond is needed to be examined in explanatory manner.
