Fluentus Residences comprises three subterranean dwellings embedded within a steep Cycladic hillside on the island of Kythnos, Greece. Conceived as an extension of the terrain rather than an imposition upon it, the project develops as a series of elongated, earth-sheltered volumes that cascade down the slope, framing expansive views of the Aegean while maintaining privacy and climatic protection.

We approached the project as a continuation of the hillside, allowing the ground itself to dictate form, section, and experience. Architecture here is not placed on the land but shaped by it.

Terrain as Generator: Embedding Architecture in the Cycladic Slope
The steep, arid topography of Kythnos operates as the primary design instrument. Rather than establishing freestanding objects, the project carves three independent dwellings into the slope, aligning their elongated plans with the natural contours. Each unit occupies a distinct elevation, creating a cascading sequence that descends toward the sea. From a distance, the built forms register less as discrete volumes and more as subtle geological modifications.
The sectional strategy is central to this approach. Roof planes fold into the hillside and are planted with native vegetation, effectively extending the terrain over the construction. Skyline exposure is reduced, and the dwellings remain visually recessive when viewed from above. The architecture behaves as a continuous topographic surface, punctuated by carefully positioned openings rather than vertical façades.
Exposed concrete in warm, earth-derived tones reinforces this reading. Its mass and texture echo the island’s rocky substrata, while the integration of green roofs enhances thermal performance and reduces visual contrast. The project aligns with a broader discourse on terrain architecture, where the ground is both context and material generator, dissolving the conventional boundary between site and building.
Sequencing, Privacy, and Thresholds in a Multi-Unit Composition
Access to the residences unfolds along a sinuous path that traces the contour lines of the hillside. The approach choreographs a gradual revelation: each dwelling appears sequentially, avoiding a single panoramic disclosure. This movement reinforces the autonomy of the three units while acknowledging their shared infrastructural logic. The winding drive and pedestrian route mediate between the scale of the landscape and that of domestic occupation.
The staggered arrangement ensures that sightlines toward the Aegean remain unobstructed for all dwellings. Private courtyards and terraces are laterally shielded by the mass of the slope and by the positioning of retaining walls. The spatial organization privileges both openness toward the horizon and seclusion from neighboring units, thereby resolving the inherent tension in a multi-residential configuration.
Thresholds are articulated through a sequence of recessed entrances, shaded patios, and semi-open living areas. These intermediate zones temper the transition from exterior to interior, responding to the Cycladic climate where outdoor habitation is integral to daily life. Overhangs and carved voids provide shelter from wind and sun, while maintaining visual permeability. The resulting spatial gradient avoids abrupt enclosure, instead establishing continuity between landscape and domestic space.
Plasticity and Material Cohesion: Concrete, Earth, and Crafted Surfaces
The formal language is defined by curvature. Retaining walls arc gently across the slope, and roof edges sweep outward in soft, continuous lines. This plasticity recalls the island’s dry-stone terrace walls, yet reinterprets them through fluid concrete geometries. The ribbed undersides of certain canopies introduce a finer tectonic articulation, registering the craft of formwork and enhancing shadow depth.
Material continuity unifies exterior and interior. Outside, exposed concrete establishes mass and permanence. Inside, micro-cement surfaces in muted earth tones preserve the shell’s tactile qualities while softening its presence. Timber slat paneling introduces warmth and texture, particularly in living spaces where vertical wooden elements counterbalance the horizontal sweep of glazing. Corten steel pivot doors and accents provide a darker chromatic register, grounding the otherwise light palette.
Natural stone elements intensify the dialogue between raw and refined. Rough-hewn kitchen islands appear as extracted fragments of the landscape, set against precisely detailed cabinetry and soft textile furnishings. In bathrooms, river stone basins rest on slender concrete shelves, paired with brass fixtures that acquire patina over time. The restrained material spectrum avoids contrast for its own sake; instead, it pursues tectonic coherence derived from the colors and textures of the Cycladic terrain.
Framing the Horizon: Spatial Continuity and Environmental Mediation
The dwellings are organized linearly along their seaward façades, where full-height glazing establishes direct visual continuity with the horizon. Living areas and primary bedrooms occupy these edges, ensuring that the sea becomes a constant spatial reference. Curved glass panels amplify the panoramic effect, softening corner conditions and reinforcing the project’s fluid geometry.
Elongated pools, positioned parallel to the façades, extend the visual axis outward. Their vanishing edges blur the distinctions between contained water and the distant Aegean, producing a layered composition of the foreground terrace, the reflective surface, and the open sea. The pools function both as climatic moderators and as spatial devices that elongate the perception of depth.
Environmental mediation is embedded in the architectural form. Deep overhangs and sculpted concrete canopies provide passive shading, reducing solar gain during peak summer months. Recessed glazing limits direct exposure while allowing generous daylight penetration. At night, the illuminated interiors read as cavities within the hillside, emphasizing the thickness of the earthen envelope rather than the autonomy of the constructed object. The project positions landscape not as a backdrop but as an active participant in shaping space, light, and habitation.
About Michail Xirokostas
Michail Xirokostas is a Greece-based architect leading the design of Fluentus Residences in Kythnos. Working with a multidisciplinary team including Theodoros Panopoulos, Anna Grigoriadou, Giorgos Telmetidis, Filio Sampsaki, Andrianos Novitski, and Angeliki Papadopoulou, the studio approaches architecture through the principles of terrain integration. Their work emphasizes earth-sheltered forms, material coherence, and a close dialogue between built space and landscape, shaping projects that emerge from the ground rather than stand apart from it.
