The project will preserve the existing apartment structures while upgrading aging exteriors and facilities, community amenities, and apartment interiors. It will retain the advantages of existing living spaces while incorporating the latest residential trends.


GS E&C is considering targeting apartment complexes where reconstruction is difficult because of high floor-area ratios or small complex sizes, and where expansion-based remodeling is not financially viable. The company estimates that around 260 complexes in Seoul alone meet these conditions.


The project’s key feature is that it will reduce construction time and costs by preserving existing structures and avoiding extensions. Without large-scale structural or civil engineering work, the company aims to complete construction in 18 months and shorten the entire project period, from planning through completion, to under three years.


The company is also considering introducing the products and residential services offered in newly built apartments. While maintaining existing floor-area ratios, it plans to make efficient use of space within each complex to expand community amenities and introduce conveniences and residential services tailored to residents’ needs.


Membership in Club Xian, which provides lifestyle services in areas such as culture, health, and care, will also be offered selectively depending on the conditions of each complex.


Residents will be able to choose floor plans and finishing materials for their homes according to their preferences. The company plans to broaden their choices and reduce costs by offering “customized options” to those seeking a space of their own, and “minus options”—construction limited to necessary areas—to those who wish to retain their existing interiors.


GS E&C plans to improve project efficiency and quality through a turnkey approach, handling the entire process from project planning and design to permitting and construction. Once the project is complete, the Xi brand will be applied to transform existing apartment complexes into new Xi communities. GS E&C plans to step up project proposals for major apartment complexes in Seoul, with the goal of signing its first project agreement next year.



A GS E&C official said, “We will reduce the financial burden on residents while improving residential convenience and the quality of our offerings, so that more customers can experience Xi’s distinctive residential value.”
