Master Planning of the Public Administration Town

‍

‍

H Architecture’s Flat City, Link City, Zero City was awarded first prize in the international competition for the Master Planning of the Public Administration Town (MPPAT) in Korea. Designed as a new 667-acre capital for national governance, the plan integrates civic identity, connectivity, and sustainability.

‍Flat City reimagines government as a unified, democratic plane—an expansive civic surface that stretches across the town, forming a public park that is open, accessible, and symbolic of transparency. Link City emphasizes connection, weaving government buildings with parks, business zones, educational institutions, and residential neighborhoods to foster interaction and functionality. Zero City sets a bold sustainability goal, incorporating advanced green technologies to minimize pollution, reuse resources, and create new habitats, aligning urban growth with ecological stewardship.

Together, these three concepts form a forward-looking model for national administration—open, connected, and sustainable.

Public Administration Town Phase 2-1

As a showcase and practical cornerstone project to lead the whole new development of the 667-acre PAT, the project has followed and elaborated H’s visions at the urban master planning phase for PAT.

The “Continuous Tangential Lines” concept, for instance, was implemented in depth at the building scale respecting the given topographical context. Breaking the traditional border between building and ground, the building mass is threedimensionally carved out from the ground level and reclaimed back to the landscaped ground. The seamless, yet dynamic integration among disparate dimensions is resonated in the spatial circulation and configuration throughout the building exteriors and interiors.

Public Administration Town Phase 2-2

With the winning scheme of the 2011 design competition for the Government Complex II of the Sejong City Public Administrative Town (PAT), H Architecture expands and elaborates our original PAT Master Plan vision of “Flat City, Link City, Zero City”, which received the highest acclaim and won 1st place at the international MPPAT competition in 2007.

H’s design for the PAT Complex II not only embodies the essence of the master plan, but also dramatically reinterprets the vision in the building scale with creative variations for diverse spatial needs and scales.

H created various optimal office spaces corresponding to unique characteristics of three governmental departments within the complex, i.e. the Ministry of Knowledge Economy, Ministry of Culture and Tourism, and the Ministry of Education, Science and Technology. Different functions were cohesively unified with multi-dimensional connecting devices including bridges and green roofs. The underside of buildings generated by pilotis structures not only creates areas of rest and recreation, but also functions as the “6th facade” accommodating way-finding graphics for visitors. Dynamic ground level configurations such as berms meet both sustainability and security needs for the complex.

As a start point of the overall curvilinear governmental complex geometry at PAT, this Government Complex II is a significant landmark and gate for the PAT. Simultaneously, H’s design lends itself to civic programs such as parks, playgrounds and occupiable roofs.
