[The Evolution of Urban Housing in Korean Metropolises and the Need for a New Approach] 1.Housing layout in Korean metropolises The existing housing layout was determined by urban collectivity, which limits the maximum benefits obtainable from housing. In the past, in our country, the distributed resources (land value) led to a process of interaction in linear buffer spaces called alleys. 2.The decline of alleys and the emergence of apartment complexes However, due to modern physical freedoms (development of internet, delivery services, etc.), the sense of community in alleys has disappeared, and the distribution stemming from urban collectivity is rather fragmenting the city. This vicious cycle leads to the decline of alleys, which in turn triggers collective asset redistribution (apartment redevelopment). As a result, the Korean-style apartment complex was born, a form of housing that maximizes land resources in terms of asset efficiency. This is a form where individual assets are symbolically concentrated and rise up 3.Problems with current housing forms I am wary of this phenomenon. It will further promote the assetization of housing and limit the potential of architecture. In our site, Seokgwan-dong, many residences are also transforming into Korean-style apartment complexes 4.The need for a new housing system To curb this, architecture must propose an alternative housing system through a new approach to housing.

[STRATEGY] Modern architecture has moved away from walls as structure 1.Setting housing axes at higher levels With the ability to use concentrated structures (reinforced concrete, steel structures), we began setting housing axes at higher levels. 2.Various benefits from this (natural light, energy efficiency, diversity of living spaces) At higher levels, there are no ground-level constraints, allowing axes to be set in any direction freely. The axes were set so that more living spaces receive sufficient natural light. This provides great benefits not only in improving residents' quality of life but also in terms of energy efficiency. Housing axes arranged considering natural light expand vertically to form living spaces. Through the vertical expansion of housing, spaces for community programs such as terraces, cafes, and offices emerge. Additionally, walls freed from structural constraints allow for flexible configuration of living spaces. This becomes an important factor in enhancing the diversity of living environments. 3.Creation of a new urban spatial structure The new arrangement creates the framework of the system by installing vertical columns on the site, which becomes the axis of new spaces at ground level. This structural innovation enables variable building forms and creates threedimensional, multi-layered spaces, moving away from the existing planar urban structure.
