The architect of Athens Tower is Ioannis Vikelas, who also designed the main building of the Goulandris Museum of Cycladic Art.

The Tower of Athens is less than 100 meters high without the antenna masts,[4] has 28 floors and is still the tallest building in Greece.

Typical is the use of glass curtains on the exterior walls of the building with aluminum frame.

[5] The Tower of Athens is built with the method of composite construction, with steel columns and reinforced concrete slabs, in contrast to other tall buildings of the time.

Because the builders didn't have expertise in the construction of large steel structures, more emphasis was placed on the reinforced concrete.

[6] Additionally, the pioneering technique of the plastic foundation was used for the building's construction, which had been developed by the professor of Statics and Dynamics of the Polytechnic School of the University of Patras, Aristarchos Oikonomou, who also carried out the statics of the building.

According to the original plan, a two-storey extended base would be built on the plot, on which the Tower would be located.
