The purpose of this study is to identify the form and components, decoration and locality of pyongnangans(平 欄干) in Yangban's Houses(32 Houses) in Gyeongbuk region, The results of this study, which were carried out through both survey and on-site study, are as below. First, Pyongnangans of Gyeongbuk region Yangban's Houses can be classified into 4 different types, which are ①Mureum type, ②Gyoran(交欄) type, ③ Mureum-Saldae combination type, ④Simplified Saldae type. And these 4 types are again subdivided into eight types, depending on differences of both detailed form and framework. Gyoran type are the most common cases in Yangban's Houses of Gyeongbuk region, whose number is followed by the order of Mureum type, Mureum-Saldae combination type and Simplified Saldae type Pyongnangans. Decorative 亞shaped Gyoran type are more set up in Sarangchaes than in Anchaes, and this was because Decorative Gyorans are more appropriate to show the Social status and class of a patriarch than humble Mureum type. Pyongnangans of Yangban's Houses in Gyeongbuk region have their peculiarities in the exclusion of decorativeity, by consistent use of plain single-layer Pyongnangans. A certain locality is reflected on the types and detailed forms of Pyonnangans. Mureum type are widely found in Gyeoungju region Yangban's Houses, while Gyoran type were more often used in Andong region. In Bonghwa region, Mureum-Saldae combination type are found in large quantities. This was due to the locational chateristics of Sarangchaes in Bonghwa region, which were usually built on steep slopes.
