**The current state of the streets in the 2020s, particularly in the side roads of Gangnam-gu, reveals a landscape where order is hard to find due to excessive business ambitions and the overwhelming self-expression of individual property owners. The aim was to contribute to improving the disordered street image while still helping business owners achieve their objectives.**
In the case of Yeoksam-dong in Gangnam-gu, due to the topographical characteristics, it is common to find shops on a lower level, such as a basement level (B1), where the site has significant elevation differences. Since the basement is not included in the floor area ratio (FAR), this allows for an additional floor in the building. This is a crucial issue for property owners, as it brings significant benefits.
With this in mind, the key design goals were as follows:
1. Ensure that the entrance road is recognized as a basement level.
2. Simplify the building massing as much as possible, particularly considering the sunlight access regulations.
3. Design in a restrained and calm manner through the selection of materials, colors, and details.
However, achieving these goals presented several challenges during the design process. First, based on the site survey, it was found that the elevation difference between the subject property and the adjacent land was not very significant. Additionally, part of the parking lot had to be accessed from a higher level, which created further difficulty. Lowering the floor height to qualify the basement level would not allow sufficient clearance for vehicle access to the parking lot. To resolve this, we hollowed out the mass above the basement to ensure enough clearance for the vehicle entrance. Additionally, the parking area was treated as a sunken space, and the higher ground level of the adjacent property was accounted for as the ground level of the basement.
In terms of the floor plan, the core was placed in the most rational location for each floor. However, the stairwell ended up being positioned in the center of the building, which affected the building's aesthetics. Typically, a stair tower is installed on the roof. In this project, we avoided this by creating a boundary between internal and external spaces in the middle of the stairwell on the 4th floor, converting the rooftop access stairs into external stairs. This change helped eliminate the need for a protruding rooftop structure and improved the design's overall coherence.
For the exterior materials, we aimed to create a restrained and calm image by using brick and transparent glass, which do not go out of style and provide a warm, timeless feel.
