A win for win for Pila. Studio and facade engineer Eckersley O'Callaghan for the redesign of the façade for the 2nd tallest tower in Greece with PILA.Studio Architects. The tower is often referred to as the ‘sleeping giant’, as the abandoned structure has in fact never been occupied except for the first three floors. The new façade will breathe new life into the building, dramatically improving its energy consumption and becoming an icon on the skyline.
