The project revitalizes an existing office building on Kifisias Avenue, built in the late 70’s, by completely redesigning the facades and core shared interior spaces, while enhancing the former structure’s enduring qualities: a rational structure with a compact central core, optimized structural grid and surrounding ribbon windows that provide ample daylight and allow for flexible floor plans for a wide range of office scenarios.
The intention of the transformation was to redefine its architectural identity, giving it an extroverted and technologically optimistic character meant to attract forward-thinking, technologically and environmentally aware tenants, while also ensuring its energy upgrade with LEED Gold certification. The transformation of this office building, situated in a prominent location of Kifisias Avenue, where Athens’ most prestigious firms are located, sends a strong signal for the reinvention of Kifisias as a vibrant business hub. This new aspiration benefits not only tenants but also visitors, the neighborhood, and ultimately the entire district, with a diverse range of uses and a lively urban activity. At night the building, with its carefully designed lighting, acts as a beacon animating the entire area and marking a new focal point.
The fluid and dynamic character of the proposed façades aims to provide the office building with a modern and elegant identity. Continuous white metal horizontal fins with a folded cross-section wrap around the floor slabs on the façades facing Kifisias Avenue, extending emphatically beyond the glass curtain walls. These elements provide solar protection and underline the stratification of the floors.
This façade design also enhances the dynamic nature of the original building’s floor plan, which consists of two primary building volumes positioned at a 45-degree angle to the rectangular plot. The curved corner of the second floor boldly projects toward the avenue, creating a distinct visual presence.
The new façades feature external aluminum curtain walls with energy-efficient glazing, allowing extensive natural light penetration. The existing building’s exposed columns are clad in aluminum with a distinctive wedge-shaped cross-section. The elevator core is also covered with the same folded aluminum surface finish.
The new interior common areas adopt a similarly innovative character, using high-quality, sleek materials. In the redesigned entrance lobby, all architectural elements contribute to creating a fluid and dynamic space. These include the undulating reception’s louvered partition, the similarly curved black anodized stainless steel reception desk, and the sinuous lighting ceiling fixture. Together, these spatial elements welcome employees and visitors while reinforcing the building’s reinvented identity.
Additional architectural interventions include functionally integrating the ground-floor office spaces with spaces of the level below by creating luminous double-height voids. These are further enhanced by adding strategical insertions of new perimeter skylights. The outdoor space at ground level is redesigned with new granite cobblestone paving and ample landscaping. The roof terrace is boldly upgraded with new shading pergola, rich planting, and improved hardscaped areas, providing a cool and calming environment ideal for relaxation and break-out functions of the new tenants.
