Sejong Government Complex

Sejong, South Korea, Asia Pacific

Completed · Civic · Ring-Shaped Government Campus · Temperate · 2014

A 620m-diameter circular government building housing 36 ministries under one continuous roofline — the world's largest ring-shaped government structure. The single-loop plan was driven by a mandate to create maximum internal connectivity across all government functions, with a central park at its core accessible to the public.

Innovation highlights

  • world's largest ring building at 620m diameter
  • single continuous structure housing 36 government ministries
  • internal connectivity without vertical circulation between ministries
  • public park as civic heart within government infrastructure
