Overview
IArc, also written as iArc Architects, is an architectural practice based in Seoul, South Korea. The firm is described as an internationally awarded practice and is associated with a design approach that seeks to create new forms of topography within the Korean architectural scene. Rather than functioning as a consumer-facing product brand, IArc operates as a professional design practice whose identity is expressed through commissioned buildings, urban interventions, and architectural experimentation. The practice is led by three partners: Kerl Yoo AIA, Jeongim Kim, and Tesoc Hah RIBA. Public reference material identifies the partners but does not provide a confirmed founding year, ownership structure, corporate parent, financial information, or a complete list of offices and international markets. Its known base is Seoul, and its documented work is strongly connected to South Korean architecture. IArc's best-known referenced projects include Miral School, completed in 1996, and the new Seoul City Hall project. Miral School was selected by KBS as one of the ten best examples of Korean architecture of the twentieth century. The practice has also received multiple architecture awards, including awards associated with the American Institute of Architects and the Korean Institute of Architects. These recognitions place IArc within the broader development of contemporary Korean architecture and help explain its international profile. The practice's positioning is design-led and architectural rather than mass-market. Its work is characterized in reference material as an effort to produce new topography, suggesting an interest in the relationship between built form, landscape, circulation, public space, and urban context. The available source material does not establish a broader commercial product portfolio, branded building systems, or consumer offerings. Accordingly, IArc is best understood as a professional-services brand centered on architectural design and project commissions. Information about the firm's current project portfolio, official website, legal entity, staffing beyond the three named partners, and present operating footprint is limited in the supplied references. Its status is therefore recorded as active on the basis that the reference describes it as an existing practice, while several corporate and historical fields remain unconfirmed.
History
IArc, also known as iArc Architects, is a Seoul-based architectural practice associated with contemporary Korean architecture. The available reference identifies the practice as being led by Kerl Yoo, Jeongim Kim, and Tesoc Hah, but does not state a confirmed founding date or provide a detailed chronology of its organizational development. One of the firm's documented early works is Miral School, completed in 1996. The project later received significant recognition when KBS selected it as one of the ten best examples of Korean architecture of the twentieth century. This recognition connected the practice with a broader reassessment of modern Korean architectural achievements and established Miral School as an important reference point in IArc's publicly described portfolio. The firm's design philosophy is summarized through the idea of creating new topography in the Korean architectural scene. In this context, topography can refer not only to physical landform but also to the shaping of spatial relationships, movement, public use, and the interaction between buildings and their surroundings. The description presents IArc as a practice concerned with architectural innovation and urban context rather than standardized building production. IArc has received numerous architecture awards, including recognition from the American Institute of Architects and the Korean Institute of Architects. The available material does not specify the individual award titles, years, juries, or projects associated with each honor. It does, however, characterize the firm as internationally awarded and places its work within both Korean and international architectural discourse. Another major project associated with the practice is the new Seoul City Hall. The reference describes it as one of IArc's newest projects, although it does not provide a completion date, the firm's precise scope of work, or project-specific award information. The project indicates the practice's involvement in significant civic architecture in Seoul. Beyond these references, publicly supplied information is limited. There is no confirmed founding year, corporate ownership data, financial disclosure, comprehensive list of offices, or complete chronology of projects. The practice is therefore documented primarily through its partners, recognized projects, architectural approach, and awards.

The new Seoul City Hall is identified in reference material as one of IArc's newer projects and represents the practice's connection with major civic architecture in Seoul. The available source does not specify the firm's exact role, completion date, design scope, or construction details, so the project is recorded as a notable architectural offering rather than described through unsupported technical claims.
