REGENERATIVE GOVERNMENT COMPLEX
Regenerative City
For nearly two decades, Thailand’s Government Complex (TGC), the nation’s most prominent governmental hub, has served as the opera
tional base for 29 government agencies across a sprawling 178-acre site.

Green Infrastructure as Urban Systems
Instead of ornamental landscaping, the complex introduces a regenerative green infrastructure network that actively restores ecological function. These systems are designed to be visible and legible, helping visitors understand how nature can operate as essential civic infrastructure. The result is a campus that performs like a living environmental engine rather than a static administrative site.

Cutting Carbon
TGC incorporates over 30% recycled materials and sources 65% locally, minimizing waste and emissions. The parking facility doubles as a rainwater-harvesting structure, using vertical blue-green systems to address flooding, air quality, and urban heat. The rooftop combines urban farming and solar panels, meeting 53.4% of the building’s energy needs, while energy-efficient systems reduce operational energy use by 87%. Rainwater flows through cascading rain chains and planters, stored in tanks and a retention pond for zero-runoff discharge, enhancing resilience during extreme weather.
Vertical Rain Garden
"The main vision is to realign the Government Complex’s physical reality with its fundamental mission: to serve its people. For decades, the campus reflected institutional priorities—order, control, separation. Our vision was to flip that entirely and create a living model of a people-first government."

Inclusivity
Public life becomes central to the complex through a series of inclusive parks, plazas, and community spaces woven between ministries. The design shifts away from bureaucratic formality toward openness and accessibility, creating democratic spaces where workers and citizens interact comfortably. dialogue—positioning government as an active, approachable presence in urban life.
Connecting
Interweaving pathways, forming functional spaces
Connecting people with various moods of speeds and activities
Cooling Corridors
Our sustainability strategy is the foundation of the design, transforming infrastructure into an integrated ecological and social system. By moving car traffic underground, we reclaimed the surface for people, replacing asphalt with Cooling Corridors of trees and bioswales that lower temperatures by 4–6°C and create shaded, walkable greenways.
Parking as Rainwater Harvesting Architecture
By upgrading rather than demolishing, the project dramatically cuts embodied carbon while modernizing comfort and operational efficiency. The buildings and landscape work as a closedloop system: shading, ventilation, water, and energy production reinforce one another. This approach demonstrates how large governmental facilities can transition toward climate neutrality without disruptive reconstruction.
