EOS Building by STARH: A Sculptural Landmark Embracing the Dawn in Varna, Bulgaria

Rising proudly along the Black Sea coast in Varna’s Chaika neighborhood, the EOS Building by STARH is more than just an architectural structure—it is a luminous homage to the goddess of the dawn. Drawing its name from Eos, the Greek deity who brings light each morning, this 6,170 m² mixed-use building is positioned at the front line of the Sea Garden, ensuring it is the first to catch the sunrise over the water.

Site-Specific Design in a Challenging Plot

Located on a narrow, triangular plot, EOS had to respond not only to the unique site geometry but also to local urban morphology. The building’s dynamic volume and distinctive silhouette emerge directly from these constraints. STARH embraced the challenge by crafting a sculptural spatial form that seamlessly integrates with Varna’s coastal skyline while maintaining a minimalist material palette rooted in white tones and horizontal layers—echoing the architectural language of the surrounding context.

Programmatic Composition and Functionality

EOS integrates residential, commercial, and office functions across its nine above-ground floors:

• Ground Floor: Includes retail spaces, a prominent entrance foyer, and an automated car lift system servicing two basement parking levels.
• Floors 2–3: Feature ateliers and modern office spaces.
• Floors 4–9: House the main residential units, designed with orthogonal internal layouts to optimize spatial efficiency and daylight access.

Despite the triangular footprint, the architects ensured that all living spaces remain rectilinear, preserving both functional clarity and architectural purity. The only exceptions are the eastern-facing loggias, which take on triangular geometries in response to the building’s sharp edge.

Structural Innovation and Material Strategy

One of the building’s most technically daring features is the series of prestressed concrete balconies on the sharper end of the triangle. These extend outward up to 8 meters on the upper floors, emphasizing the building’s dramatic profile and maritime orientation.

EOS was also designed with long-term sustainability and durability in mind. The façade is composed of a ventilated fiber cement system (Swisspearl’s Colorline - Reflex), ensuring low maintenance and strong thermal performance. Aluminum joinery, high-selectivity glazing, and Saint-Gobain insulation systems work together to create a low-energy, high-comfort envelope that withstands coastal conditions.

Architectural Aesthetics and Living Experience

The interiors reflect STARH’s commitment to contemporary minimalism and spatial clarity. Clean lines, floor-to-ceiling windows, and open-plan layouts characterize the apartments, offering sweeping views of the Sea Garden and the Black Sea. The combination of form, materiality, and function ensures a refined urban lifestyle in one of Bulgaria’s most desirable coastal settings.
