KPLN’s Nature-Inspired Kavkaz Airport Terminal in the Caucasus

Few airport terminals invite passengers to forget they are in an airport. The new Kavkaz Airport terminal, designed by KPLN for the mountain resort region of Arkhyz in Russia’s Karachay-Cherkess Republic, does exactly that–using the Caucasus landscape itself as the generator of form, material, and spatial sequence. Set on the banks of the Bolshoy Zelenchuk River, the 27,028 sqm building replaces the conventional airport experience with one that channels forest foothills, mountain lakes, and the graceful geometry of fir seeds. When it opens in 2029, the terminal will serve as the primary aerial gateway to Arkhyz, Dombay, and Elbrus–three of Russia’s most significant mountain destinations.

Reading the Caucasus Landscape as an Architectural Brief

KPLN’s design for the Kavkaz Airport terminal begins with a simple proposition: an airport in the mountains should feel like it belongs to the mountains. The Arkhyz region–known for forested foothills, glacial lakes, and meadow-covered hills–provided both the visual language and the organizational logic for the building.

The terminal adopts a triangular footprint with rounded corners, its massing kept low and horizontal to align with the terrain rather than compete with it. A continuous green roof extends from the landscape up and over the building, effectively dissolving the boundary between architecture and topography. Internally, a courtyard-atrium planted with fir trees reinforces this continuity, bringing the external environment into the passenger circulation path.

The most distinctive structural gesture appears in the V-shaped timber columns that support the roof throughout the terminal. Chief architect Sergey Nikeshkin describes them as evoking pine needles–an explicit biomorphic reference that transforms a structural necessity into a narrative device. These columns, combined with a slatted timber ceiling and panoramic glazing oriented toward the runway and mountains beyond, create a spatial rhythm that recalls walking through a forest clearing rather than waiting for a flight.

The functional program follows a linear sequence: entrance and check-in, retail and food court, security, VIP lounge, and finally the departure hall with its panoramic mountain views. This progression mirrors the experience of moving through a landscape–each zone a distinct terrain.

Design Decision: Rather than treating the green roof as a cosmetic afterthought, KPLN used it as the primary massing strategy--allowing the building to read as a continuation of the hillside. This choice significantly reduces the visual impact of a 27,000-square-meter structure in a sensitive mountain landscape.

Moving Through the Terminal: A Spatial Sequence

The Arrival Canopy — A Forest of Timber Columns

The passenger experience begins at the drop-off zone, where a sweeping canopy supported by V-shaped timber columns creates a sheltered threshold. The columns splay outward as they meet the ground, echoing the branching structure of pine trees and establishing the terminal’s dominant architectural motif. From this point, the green roof is visible as a continuous landscaped surface–passengers arriving by car move directly from the open air into a space that feels closer to a mountain lodge than a transportation hub.

The Departure Lounge — Where Waiting Becomes Viewing

Inside, the main departure hall reveals the full spatial ambition of the project. The V-shaped timber columns rise to support a slatted wood ceiling fitted with linear lighting, creating a warm, rhythmic interior that recalls sunlight filtered through a forest canopy. Floor-to-ceiling glazing along the airside facade offers direct views of the runway and the mountain landscape beyond, turning the wait for a flight into an experience of the place. Seating areas are arranged in clusters, with islands of retail and food service integrated into the open plan.

The Courtyard-Atrium — Architecture as Living Landscape

Perhaps the most unexpected space in the terminal is the courtyard-atrium, where a landscaped green hill rises through the building, creating an indoor terrain planted with fir trees. This is not a decorative atrium–it is a central orienting device that organizes circulation and provides a moment of calm within the typically stressful airport environment. A coffee house embedded into the hillside demonstrates how the architecture treats building and topography as a single continuous surface.

A Bold Vision for Regional Air Travel — With Inherent Complexities

* What Works Exceptionally Well

The integration of the green roof as a primary massing strategy is the project’s strongest move. By allowing the building to read as a continuation of the hillside, KPLN has solved the fundamental problem of placing a 27,028 sqm industrial structure in a sensitive mountain landscape without diminishing its functional capacity. The biomorphic column strategy is equally successful–the V-shaped timber supports unify structure, aesthetics, and narrative in a single gesture that gives the terminal a recognizable identity.

The linear spatial sequence, moving from check-in through retail and security to the panoramic departure lounge, demonstrates a clear understanding of passenger flow. Each functional zone is distinct without breaking the continuous spatial experience.

* Practical Considerations & Limitations

The green roof and courtyard-atrium, while visually compelling, introduce significant maintenance demands in a mountain climate with heavy snowfall and temperature extremes. The long-term viability of the living roof system and the health of the planted fir trees in an enclosed atrium will require sustained horticultural management that many airports struggle to resource.

The extensive use of timber structural elements and panoramic glazing also raises questions about thermal performance in a region where winter temperatures drop well below freezing. The balance between the aesthetic priority of transparency and the operational need for thermal efficiency remains to be proven once the building enters service.

What It Means to Build an Airport That Disappears

KPLN’s Kavkaz Airport terminal makes a persuasive case that transportation infrastructure in sensitive landscapes should not announce itself as infrastructure. By allowing the Caucasus mountains to generate the building’s form, materials, and spatial character, the architects have created a terminal that functions as a gateway in the most literal sense–it introduces visitors to the landscape before they have left the building. The project is best suited for travelers who understand that architecture can be both efficient and deeply place-specific.

Would you accept the maintenance complexity of a living green roof if it meant your local airport felt like a park rather than a warehouse?
