Sanko HQ
Istanbul - Turkey 

The Sanko Headquarters development in Istanbul, Turkey, is the winning design of the competition for Sanko Holding, one of the oldest banking groups in Turkey. The site has been recessed to create parking for the users to maximise the ground level for pedestrian activities with the main entrance to the building is from the South-East corner.

The basic mass has been formed by extruding the site based on the maximum usable volume. The volume was stretched and modelled to create a dialogue with the surrounding area. The form, along with the fenestrations, appears to be shaped by the forces of nature. The central void extends from the ground up to the roof of the building for an implosion of light. Each floor, from the upper floors right down to the auditorium, hosts different greenery which improves the quality of the ambient air.

The outside greenery contrasts solar radiation, making the inside of the building cooler and reducing the need for air conditioning. The building consists mainly of offices and meeting rooms, an auditorium and a restaurant on the lower floors. The service and parking spaces include an innovative system that stores rainwater to be re-used for watering the greens on each floor and other non-potable use.
