What Gansam Architects & Partners does
Gansam Architects & Partners (간삼건축종합건축사사무소) is a Seoul-headquartered, privately held architectural design and construction management firm founded in 1983. It provides integrated services spanning architectural design, landscape and interior design, urban planning, structural engineering, construction management (CM), and space branding/consulting, serving Korean conglomerates, government agencies, higher-education institutions, and developers. Headcount exceeds 700 staff, including 140 licensed architects and 50 professional engineers, organized into specialized design studios (data centers, cultural, hospitality, healthcare, residential, high-tech) and a CM division, with Seoul headquarters plus regional offices in London and Atlanta.
The firm's revenue model is project-based professional services, with fees quoted per engagement and revenue generated across three primary streams: architectural design services, construction supervision/CM, and space branding/consulting delivered through its wholly owned subsidiary Gansam Business Initiative. Distribution is enterprise field sales — Gansam wins work through design competitions and direct engagement with anchor clients (LG, Samsung, Hyundai, SK On, Hanwha, Kakao), and operates additional lifestyle/hospitality brands (GHED, Co.Village, Tiny Resort) that extend the brand into consumer-facing and rural development markets. Go-to-market is overwhelmingly project-based enterprise sales to large Korean conglomerates and government, supplemented by international commissions through the London and U.S. subsidiaries.
Gansam's technical positioning is anchored in three specialized domains: data center design (77 cumulative projects, including seismic isolation and liquid cooling firsts), UAM (Urban Air Mobility) vertiport infrastructure (first Korean firm in the space, contributed to national standards/legislation), and mass timber multi-family construction (Korea's first mass timber apartment complex). The firm pairs these specializations with global design partnerships — Tadao Ando (LG Arts Center Seoul), Thomas Heatherwick (Nodeul Global Art Island), and Wilmotte & Associés (Centre Pompidou Hanwha) — positioning Gansam as the Korean local-architect partner of choice for internationally renowned cultural and landmark commissions.
