This study presents the features and characteristics of Double-hung windows, which are major components in the Western Modern Architecture, based on 53 Modern Architectural Heritage of Korea focusing on their external design. The results are shown below. Firstly, as a result of analysis in the architectural features of the Double-hung window, the lintel and sill were installed at the same time due to the technical limitations of that time. Secondly, after analysing the width and height of the Double-hung window, the ratio of the horizontal and vertical was 1:1. This determines that the Double-hung windows had the square forms in general at that time. Furthermore, it had the ratio of 1:2.2 by the vertical arrangement. If the ratio were larger than 1.:2.2, the arch and upper window were added. Thirdly, by analysis the relationship between the floor and window height, it shows that the ratio between them are 1 : 0.4(Max)․ 1 : 0.8(Min)․1 : 0.6(Ave). Therefore, the floor height determines the Double-hung Window height. If the floor height changes its size, the window height will change accordingly. Fourthly, the numbers of mullion maintained the certain basic forms. From the subjects of this study showed 21 numbers of 2×2 mullions and 14 numbers of 3×3 mullions which showed that the equal division was preferred at the time. And lastly, in order to create the elevation with visual effect, the Double-hung window used various highlight techniques which are, particularly, increasing numbers of mullion, symmetry forms in upper and lower mullion and emphasising on its mouldings.
