The Moon2 Spa complex is a 260 m2 wellness interior embedded at the base of a mountain hotel in Arkhyz, Russia, where board-formed concrete, thermal water, snow, and panoramic glazing establish a direct spatial relationship with the Caucasus landscape.

The space is designed maximally laconically: architecture itself shapes the interior environment. Light, proportions, and material become the main tools creating the atmosphere.

Mountain Context and Embedded Volume
The spa occupies the lower portion of the Moon2 hotel, where the building meets the steep terrain of the Arkhyz ski area in the Caucasus Mountains. Rather than treating the wellness area as an autonomous interior, the project situates it at the interface between architecture and slope. This position gives the spa a geological reading, as if the rooms had been cut into the mountain base and opened selectively toward snow, forest, and distant peaks.
The exterior combines board-formed concrete, weathered timber, glass, and winter ground cover in a restrained material field. The concrete base gives the building a sense of weight, while the timber-clad upper volume reads as a lighter structure set above it. Irregular openings interrupt the mass with varying degrees of exposure, from narrow slots to broad glazed panels that reflect the surrounding snowfields and sky.
Terraces and full-height windows organize the landscape experience through framed views rather than continuous transparency. The spa does not dissolve entirely into its setting; it alternates between enclosure and exposure. This calibrated relation to topography allows the mountains to function as more than scenery, becoming a spatial boundary, a light source, and a climatic condition that shapes how the interior is perceived.
Concrete as Interior Landscape
Inside, concrete is used with an unusual degree of continuity. Walls, ceilings, floors, pools, and stairs are treated as parts of a single interior terrain, giving the spa a carved quality. The material is not presented as a neutral finish or an industrial reference. Its roughness, density, and tonal variation position it closer to rock, aligning the interior with the mineral character of the surrounding mountains.
The reduction of furniture strengthens this reading. Black leather loungers, low benches, small metallic tables, and a limited number of softer elements appear as secondary insertions within a dominant concrete field. The absence of conventional spa decoration shifts attention toward proportion, shadow, waterline, and texture. In this context, the pool edge, stair soffit, and ceiling plane become the primary architectural elements.
Several rooms include natural boulders placed directly against concrete surfaces. These objects risk literalizing the project concept, yet they also clarify the intended ambiguity between constructed mass and geological presence. Brass and bronze accents, along with occasional polished or backlit stone elements, introduce moments of contrast without overturning the overall severity of the material palette.
Thresholds Between Interior and Exterior
The pool is the central threshold device in the project, extending across the boundary between enclosed spa rooms and the open mountain air. Part of the basin lies inside, while another portion reaches outward into the cold exterior. The separation between the two conditions is handled through large operable glazing, allowing the transition to remain visual and atmospheric rather than simply functional.
This threshold is repeated throughout the spa in pivot doors, covered concrete passages, glazed corners, outdoor showers, terraces, and thermal pools. Movement through the project is gradual, passing from dark mineral rooms to sheltered exterior edges and then to open snow-covered ground. The architecture avoids a simple binary between inside and outside, instead producing a sequence of climatic zones with varying degrees of protection.
Steam rising from the outdoor water, snow accumulating around stone and concrete edges, and warm light spilling from the interior all make weather part of the architectural composition. The thermal pool gains intensity because of its exposure to cold air. In this sense, the spa does not neutralize the mountain climate; it uses the contrast between heat and winter as one of its principal spatial materials.
Light, Atmosphere, and Ritual
Daylight enters the spa through panoramic glazing and a circular skylight above the main pool hall. The oculus gives the room a clear center and introduces the lunar reference suggested by the project name without relying on applied ornament. Its geometry contrasts with the heavy concrete envelope, drawing the eye upward while keeping the body anchored to water and stone.
The dark tonal range of the interiors produces a cave-like atmosphere, but the project avoids complete enclosure through carefully placed openings. Mountain views appear at the end of rooms, across pool surfaces, and beyond relaxation areas. Reflections in water and glass soften the mass of the concrete, while the low level of furnishing encourages a slower reading of the space as a sequence of rituals rather than a collection of amenities.
At night, the architectural language changes significantly. Red, blue, amber, and turquoise lighting recast the concrete rooms as theatrical chambers, with glowing water, illuminated stone panels, and colored sauna spaces visible through glass. This lighting strategy introduces tension into the project: the calm mineral character of the daytime interior gives way to a more staged atmosphere, where wellness is framed through color, reflection, and controlled intensity.
About Architectural Studio Chado
Architectural Studio Chado is the architecture studio credited for the Moon2 Spa complex at the Arkhyz ski resort in Russia. In this project, the studio develops a laconic spatial approach in which concrete, light, proportions, panoramic glazing, and the mountain context shape an interior environment perceived as a continuation of the surrounding landscape.
