Through 16-17th century, Neo-Confucianism was accepted and extended to Chosun Dynasty. The architecture of the Taegae school made buildings of Yongnam area rich by adding the regional characteristics based on Taegae's thought of architecture. The following is the architectural characteristics of the academic clique around Sangju. Transformation such as separation and combination of the Jeongsa space by function, lifted floor type reflecting local feature or high platform was appeared, and the architectural characteristics of the Taegae school, that is, a small scale, a moderate figure, a type of side-attached floor, landscape, were still maintained at the same time. The characteristics of the Taegae school and regional figure of Sangju were well joined. The upper class houses, Seodang, Jeongsa and Seowon, built by Confucianist had shared common Confucian characteristics in spite of their different purposes. The world view of the Confucianism such as sacrifice for sages, cultivation, devoting for study, teaching disciples, and education for villagers was revealed through the Confucian architecture including dwelling houses during the 16-17th century. Buildings of Confucianist were focused on the space for men. Seoae and Kyumam built two different Jeongsa's inside and outside of the boundary of the nakdong river. While Seodang and Jeongsa located outside of the boundary of the river were built excluding spaces for living, the function of the Jeongsa located inside of the boundary of the river was assimilated by Sarangcahe. However, both buildings kept the function for cultivation, devoting for study and teaching.
