Koh Phangan Airport: A New Benchmark in Sustainable Airport Design

Koh Phangan Airport, located on the island of Ko Pha-ngan in the Gulf of Thailand, represents a transformative approach to sustainable airport design. Designed to accommodate approximately 600,000 passengers annually, this project challenges conventional airport typologies by integrating environmental sensitivity, spatial efficiency, and experiential architecture.

The project, developed by Alexander Stankevich and recognized as a Winner entry of First Window, proposes an airport that is not only a transport hub but also a landmark that resonates with the island’s ecological and cultural context.

Rethinking Airport Architecture Through Sustainability

Unlike traditional airport terminals that prioritize scale and throughput over context, Koh Phangan Airport introduces a site-responsive sustainable airport design strategy. The architecture minimizes environmental intrusion while maximizing operational efficiency.

The terminal is carefully embedded within the terrain, responding to the island’s mountainous topography. This reduces visual impact while maintaining strong connectivity between land, air, and passenger movement systems.

A key aspect of the design is its emphasis on zero carbon ambitions, aligning with global sustainability goals. Passive strategies, material optimization, and efficient zoning contribute to reducing the building’s environmental footprint.

Multi-Level Circulation and Passenger Flow Optimization

One of the defining features of this sustainable airport design is its multi-level circulation system, which separates arrival and departure flows across different elevations.

• Ground floor (-6m): Arrival zones and service functions
• Level 0m: Departure interface and passenger processing
• Upper levels (+8m, +14m, +16m): Structural and operational layers including roofing and insulation systems

This vertical organization eliminates cross-flow conflicts, ensuring seamless passenger movement while meeting international Level of Service (LOS) requirements. The clarity of circulation enhances both efficiency and user experience.

Modular Zoning and Functional Flexibility

The airport’s zoning strategy reflects a highly adaptable and modular sustainable airport design approach. The terminal is divided into three primary zones:

• Domestic operations
• International operations
• Technical and management functions

This segmentation allows the airport to scale operations dynamically based on demand. The design also accommodates future expansion without disrupting existing infrastructure, making it resilient and future-ready.

Integration of Culture, Commerce, and Experience

Beyond functionality, the project redefines the airport as a multi-functional public space. Interior spaces are designed to host cultural exhibitions, recreational areas, and commercial activities inspired by Koh Phangan’s local identity.

This approach transforms the airport into a curated experience rather than a transitional space. Visitors are introduced to the island’s culture upon arrival and leave with a reinforced memory of place.

Structural Expression and Architectural Identity

The architectural language of Koh Phangan Airport is defined by fluid, organic forms that echo natural patterns. The roof structure, composed of lightweight metal frameworks and layered insulation systems, creates a dynamic silhouette.

The sweeping geometry is not merely aesthetic but also functional. It enhances natural ventilation, daylight penetration, and thermal performance, reinforcing the principles of sustainable airport design.

The façade integrates transparency and structural rhythm, allowing visual continuity between interior spaces and the surrounding landscape.

Site Planning and Infrastructure Strategy

The site plan demonstrates a comprehensive integration of airport infrastructure, including:

• Runway (1100m length)
• Passenger terminal
• Aircraft maintenance areas
• Air traffic control systems
• Parking and highway connectivity

The layout ensures efficient aircraft movement while maintaining minimal disruption to the natural terrain. The inclusion of business aviation, cargo, and security zones highlights the project’s operational completeness.

Future Expansion and Long-Term Vision

A critical strength of this sustainable airport design lies in its capacity for phased expansion. The modular planning allows the airport to grow from its initial capacity to over 1 million passengers annually.

Expansion strategies are embedded within the masterplan, ensuring that growth does not compromise design integrity or environmental performance.

Koh Phangan Airport sets a new precedent in sustainable airport design, where infrastructure, environment, and user experience converge. By reimagining circulation, integrating cultural narratives, and prioritizing ecological sensitivity, the project transcends conventional airport architecture.

As global aviation moves toward sustainability and adaptability, this project offers a compelling model for future airport developments worldwide.
