NBG Office Headquarters (Megaron Karatza) / Athens, Greece2017
National Bank of Greece Office Headquarters (Megaron Karatza) / 1st Prize, Invited Architectural Competition, Mies Van Der Rohe Award for European Architecture (Nomination)
The building completes the corner of an important building block of the historic center of Athens. It comprises of a basic volume, parts of which are subtracted in such a way as to maintain the readability of the primary volume. Its main elevation on Aeolou Street is in close dialogue with the neighboring neoclassical Main Building.
A hierarchy of facades, readability of floorplans, use of geometry and symmetry, simplicity of form, together with the relationship of the building to the archaeological findings and the natural light, represent the basic themes of the composition.
The void in the interior lets natural light to enter. Space expands from the moat of the ancient wall, 9 m. below, visible through the glass floor of the 1st floor, to a height of 17 m. to the skylight on top. What becomes subtracted from the volume, what from mass changes to void, is flooded by light that becomes a strong compositional element.
