Art 1 Office in Athens

Constellation of volumes

An existing 40-year-old office building is stripped back to its primary structure and comprehensively reinterpreted to respond to contemporary workplace demands. The initial massing logic is recovered and clarified, transforming what was once a fragmented and visually inconsistent assemblage into a cohesive composition. The building is rearticulated as a constellation of twelve distinct volumes, each defined by its own cladding strategy and spatial atmosphere, establishing a new architectural identity rooted in differentiation and clarity.

 

Intervention Strategy

The intervention operates through a process of subtraction and redefinition. By removing non-essential layers, the original structural framework is revealed and reorganized, allowing the building’s inherent geometry to be legible once again. The front façade adopts a restrained material palette, articulated through subtle tonal variations of white, grey, black, and gold. A newly introduced curtain wall defines the primary elevation, while a sequence of cast-in-place terrazzo steps establishes a clear and generous entrance gesture.

In contrast, the rear elevation embraces a more expressive and playful language. Individual volumes are distinguished through color and material differentiation: a pale turquoise-clad elevator core, a striped black-and-white staircase punctuated by yellow window frames, a pink-rendered service core, and blue metal-clad office spaces. This chromatic distribution extends throughout the building, generating a dynamic interplay between interior and exterior surfaces.

 

 

Spatial Organization & Environmental Strategy

The building is reoriented to engage more directly with its adjacent natural park, introducing new openings within previously opaque façades. These interventions enhance visual connectivity while significantly improving daylight penetration, addressing the limitations of the original low ceiling heights.

At roof level, a landscaped green roof is combined with a circular pergola, forming a sequence of outdoor workspaces and social areas. These elevated spaces accommodate informal gatherings, events, and moments of exchange, extending the program beyond the conventional office environment.  

Sustainability is integrated as a core design parameter. The project incorporates high-performance insulation systems, energy-efficient glazing, locally sourced materials, and low-energy mechanical systems. Additional features include photovoltaic panels, electric vehicle charging stations, and bicycle parking, contributing to the building’s A+ energy efficiency rating.

Material Palette

The interior design negotiates between preservation and transformation. Existing black marble flooring is restored, while suspended ceilings are removed to expose the raw concrete structure and its irregular formwork. This juxtaposition of refined and unfinished surfaces establishes a consistent material language across all levels.

Each floor is further differentiated through bespoke architectural elements and furniture interventions. These range from sculptural marble seating installations to a vivid red perforated metal library and expansive shared worktables. On the ground floor, a generous red terrazzo staircase operates simultaneously as circulation and as an amphitheatrical space for events, linking to a luminous mezzanine above.
