Space analysis aims to identify the relations between society and space. Space analysis results let us identify the characteristics of the targeted space and subsequent human activities based on the notion of social relationship. The reason authors try to understand spatial structure lies in that it is the intrinsic attribute of physical built environment. This research looks into apartment houses, a widespread form of housing in Korea, in an attempt to investigate the social logic lying in its domestic space by measuring the spatial configuration. This research is based on empirical data and uses a quantitative methodology; Space Syntax. Characteristics of spatial structure in apartment units and their meanings were identified through this research. The implication of the living room-centered layout type most common in Korean apartments was discussed from the viewpoint of the domestic space genotype.

This study attempts to verify the validity of the neighborhood unit theory in Korea and interpret its meaning. In Korea, Perry's neighborhood unit theory has been applied to new cities and housing block plans as a design principle since its introduction. While the theory has been actively applied to New Town developments throughout the world, it has also faced criticisms. This paper begins with the question 'Does Perry's theory still have viability in Korea?' First of all, this research reviewed the major contents and corresponding examples of Perry's theory. In attempts to answer this question, major contents of the controversies were summarized historically, along with reviews on the background of how Perry's theory was introduced. This is followed by examinations of applications of the neighborhood unit theory in Korea. Additionally, solutions regarding criticism of the theory were diagnosed. It was also pointed out that although there was a time that Perry's theory was applied uniformly during socioeconomic changes in Korea, there were efforts to overcome the limitations of this theory. As a result, it was found that the neighborhood unit theory still viably suggests basic design principles for various types of planning from residential planning to life zone planning.

The objective of this research is to investigate the periodic changes in external spatial configuration of Korean apartment complexes and their planning concepts with quantitative spatial analysis methodology, for the purpose of comparatively analyzing the results with the relevant social, economic climate of its period. Based on the axial map analysis method, we established a spatial configuration analysis model of apartment complexes by setting the relevant analysis indices and criteria for periodic, spatial classification. One-way ANOVA was applied to the periodical indices of integration and PD for each spatial component, and then the periodical mean values of the indices for each spatial component were calculated to make comparisons across the periods. The results revealed that differing planning initiatives according to each period were not only reflected in the spatial configuration of the apartments in their entirety, but that it was also possible to extract key elements in planning which made up the apartments in that particular period.

Although the Korean government has provided high-quality architectural building information for a long period of time, its focus on administrative details over three-dimensional (3D) architectural mapping and data collection has hindered progress. This study presents a basic method for extracting exterior building information for the purpose of 3D mapping using deep learning and digital image processing. The method identifies and classifies objects by using the fast regional convolutional neural network model. The results show an accuracy of 93% in the detection of façade and 91% window detection; this could be further improved by more clearly defining the boundaries of windows and reducing data noise. The additional metadata provided by the proposed method could, in the future, be included in building information modeling databases to facilitate structural analyses or reconstruction efforts.

Due to the growing interest in eco-friendly and sustainable design in the architectural and urban planning field, we are witnessing numerous projects in which old buildings are being reused. However, with the exception of domestic apartments, there hasn't been a systematic approach or policy regarding the reuse of specific building types. On the other hand, we were able to point out two public building types, dong-offices and primary schools, that are expected to be underused, with future needs for conversion. Because the two building types are public buildings, we believe that their conversion must address the needs of the society. In this study, we have chosen 'social integration' as the ultimate goal of reusing public buildings. Upon the conceptual model of 'Housing-Mixed Public Facility', which was produced in a previous study, we have added other core programs that could be adopted into the model. Then, we applied the improved model onto the two building types by producing conversion plans and introducing key planning techniques. During this process, we have found some regulations that would not allow the realization of some models. Therefore, we have suggested amendments to the related regulations.
