“Olin” Project: Architecture in Harmony with Syros Terrain

Integration of Buildings with the Natural Environment

Along a tranquil coastline on the Greek island of Syros, one can observe how modern buildings are seamlessly integrated into the natural landscape without visually disrupting it. A prominent example is a small hotel project consisting of seven suites, designed to be partially carved into the rocky slopes overlooking the Aegean Sea. This construction approach allows the building to blend with nature rather than assert itself as a separate architectural element.

Design Sensitivity to the Site

The area is characterized by rugged terrain and continuous sea views, requiring architects to carefully consider how to interact with the surrounding environment. In such cases, the goal is not merely to create a new facility but also to respect the site’s existing natural character. The terrain is strategically employed to conceal parts of the building, making the design appear as a natural extension of the slope itself and enhancing the sense of harmony between architecture and nature.

Architecture in Harmony with the Terrain

What makes this project particularly distinctive is the way the architecture is shaped to interact with its surroundings. Rather than relying on prominent, attention-grabbing building forms, the design emphasizes elements such as terraces, retaining walls, and precise cuts into the land. These components create a series of spaces that gradually unfold as one moves along the slope, making the building appear as a natural part of the landscape rather than imposing itself upon it.

Terraced Design and Gradual Perspective

The project extends along the slope in a terraced manner, allowing movement through the site to offer a transitional experience from public areas to private spaces. For instance, open terraces reveal expansive views of the Aegean Sea, while more secluded and secure rooms are positioned deeper within the slope. The walls, finished in warm, earthy tones with a refined texture, further enhance this harmony with the surrounding rocks, making the architecture feel like an integral part of nature rather than a separate element.

Spatial Organization Across Different Levels

The resort is designed around three main levels, referred to as the “Level,” the “Line,” and the “Point,” each connected by a winding path that gradually guides visitors down the slope. This gradation allows the experience to transition from public spaces at the top to increasingly private areas as one approaches the lower part of the site.

At the top of the project lies the “Level,” serving as the social hub of the resort. It is enclosed by a curved retaining wall and features a wide terrace overlooking the sea. A leaf-shaped design canopy provides sun protection while creating a visual harmony with the surrounding environment. The pool reflects the distant sea horizon, adding an aesthetic dimension to the space.

Interior Space Distribution

Below the terrace, shared interior design areas and a single bedroom are carved into the slope, while three additional bedrooms extend in simple cubic forms, framed to offer direct views of the sea. This layout embodies the idea of combining openness to the natural surroundings with individual privacy, demonstrating how intelligent design can use the terrain to create a gradual, balanced experience.

Retaining Wall and Curvature as a Design Element

The wide curvature of the retaining wall is one of the defining features of the design, creating a sense of enclosure and protection without restricting openness to the surrounding landscape. This approach allows the terrace to remain completely open, providing uninterrupted views of the sea and the surrounding space, and enhancing the harmony between the building and nature.

Middle Level: “The Line” and the Flexible Unit Experience

Along the slope lies the level known as “the Line,” which houses two larger underground suites. Each suite can function as an independent accommodation unit or be combined to form a larger living space, offering flexibility in use. The units open onto a shared terrace featuring a long, narrow infinity pool that stretches toward the horizon, reinforcing the visual connection with the sea and the surrounding natural environment.

Lower Level: “The Point” and Residential Seclusion

At the bottom of the site is the most secluded section, known as “the Point,” representing a private space for guests seeking privacy. The building is enclosed by a curved stone wall and includes a small circular pool. Exposed rocks at this level provide a subtle contrast with the painted walls elsewhere in the project, adding a natural visual dimension and enhancing the sense of integration with the terrain.

Interior Design Focused on Environmental Harmony

The interior décor is designed to evoke a sense of calm and lightness, despite many spaces being carved into the slope. Soft white tones play a key role in reflecting natural light throughout the rooms, while light stone flooring creates a visual connection between interior spaces and the outdoor terraces. This continuity helps blur the boundaries between inside and outside, enhancing the sense of comfort and openness.

Experiencing Movement Through Natural Spaces

From an architectural perspective, the building feels less like a structure placed on the terrain and more like a natural extension of it. The architecture follows the slope of the hills, gradually opening toward the sea while remaining rooted in the hillside. Visitors move through terraces, shaded pathways, and rooms carved into the slope, maintaining a continuous awareness of the surrounding horizon. In this way, the experience of staying in the resort becomes more than just a place to sleep, it transforms into an interactive engagement with the natural landscape, making coexistence with the environment an integral part of the design.

✦ ArchUp Editorial Insight

The “Olin” project in Syros emerges as a response to financing visions and land division policies that prioritize minimal visual impact while maximizing returns from limited coastal plots. Purchase restrictions and labor costs dictated a terraced arrangement of spaces, allowing accommodation units to be positioned progressively along the slope, thereby mitigating regulatory complexities and fluctuations in construction costs.

The resulting layout, stepped slopes, partially buried units, and interwoven pathways, functions as a procedural solution balancing population flows and site compliance requirements, rather than as a consciously architectural statement. Shaded paths and open façades act as mechanisms to extend operational control and reduce external risks.

Overall, the project appears as a tangible record of interactions between capital, regulation, and logistics, where every spatial choice encodes the rigidity of prior financial decisions and the class disparities in the market, rendering the architect invisible and systemic forces overtly visible.
