The Ziraat Bank headquarters is conceived as the centre piece of the Istanbul International Financial Center (IIFC), the design of the landmark twin towers integrates highly crafted detail with the demands of a modern workplace and draws on the architectural and cultural heritage of one of the world’s oldest and most diverse cities.
The office towers extend more than 350,000m2 and rises to 40 and 46 storeys, incorporating Ziraat Bank Headquarters, ground floor retail, and below grade parking. Designed to support employee-wellbeing collaboration, and social interaction across floors. Varied workplaces and shared amenities are provided, such as prayer rooms and naturally ventilated, double-height atria and roof terraces.
Designed as independent but interconnected buildings, the podium links the towers, providing a common entrance and amenities. Bridges cross the eight-storey atrium at multiple levels, promoting connectivity across the buildings. On the street and plaza levels, the space within the podium is envisioned as a continuation of the IIFC’s civic space and is defined by the sculptural form of the free-standing auditorium.
Throughout the building, high-quality local stone and wood details are incorporated, most notably in the auditorium, which is clad in double-curving panels of CNC milled, local limestone. Internally, the auditorium is lined with timber to create a sense of intimacy, the waving profile of the roof panels was modelled to improve acoustics.
The detailing of the podium façade references the ornate screens used across Islamic architecture, adding texture and layering while tempering the light to protect the interior from glare and overheating. The towers display a more contemporary style as they rise serving as a landmark to the growing district. Louvers arranged in horizontal bands, and varied according to height and orientation, are utilised to allow high levels of internal daylight across the office floors whilst preventing excessive solar gain.
