A Tall Building at the port of Piraeus – the Piraeus Municipality belongs in the urban area of the city of Athens which has a population of 4,000,000 – is abandoned for more than 30 years. It is 22-storey building, 84 m. tall and it is known as "Piraeus Tower". It is often called as "the sleeping giant" due to its abandonment. The only tower of the area is "sleeping" in one of the bigger ports of Mediterranean that presents a dynamic growth the last decades.

There is a challenge, therefore, in order for the Tower to become a landmark at the port of Piraeus and to be highlighted, with its modernisation, as one of the most important architectural buildings not only for the city of Piraeus but for the whole city of Athens.

The challenge is focused to the reconstruction of the external facade of the building. The facade interventions regard the type and dimension of the proposed constructions either in contact or at a distance from the existing curtain walls. The interventions may be surfacings, facades renovations, constructions of every type and size, or all of them. The proposed interventions may be extended over the building within the ground boundary without, though, any height limitation. Every vertical or horizontal construction cannot be occupied by indoor spaces. The building indoor space is still in the existing outline. The frame of the building shall be kept without any intervention. However, additional support provisions shall be introduced where appropriate and necessary.
