By the late 1930s, ten years after its establishment, the Bank had a staff of over 2,000 (in his “Chronicle of the Bank of Greece”, Ilias Venezis places the exact number at 2,061: 1,714 men and 347 womennotes), while its operations kept expanding. Thus, even before the head office was inaugurated in 1938, there had already been talk of its extension.
After World War II, the building was initially expanded towards Omirou and Edouardou Lo Streets and later, by the 1970s, to Stadiou Street, thus covering the entire block (more than 6000 m²). The latter project was designed and supervised by the Technical Service led by architect A. Papanastasiou, on plans by architect N. Sapountzis and with E. Vourekas as consultant architect. Visible in this new wing are post-war architectural perceptions and a harmonious blend of different styles in the new façade on Stadiou Street.
Addition of a fifth floor
A fifth floor was added in1982, designed and supervised by architects E. Dalaklis and I. Karagiannakis. The project was led by N. Sapountzis, while E. Vourekas was engaged as as consultant architect.
