The apartment block of S70K was designed by Ilias Papagiannopoulos in 1977 in Kolonaki, influenced by the works of Le Courbisier. The building is a typical example of Papagiannopoulos' design, with the interlocking of the canoe with the front on the boundary of the warped plot. The fact that Papagiannopoulos designed a structural shell by moving the entire load-bearing system outside the building makes the building interesting in terms of its structural system. Details separating the floor and the wall or the wall and the ceiling are observed inside the building. The designed relief of the entrance at the entrance also reflects the architect's artistic characteristic. All his life Elias sought to combine painting and sculpture with architecture. The S70K apartment was redesigned and renovated by taking these details into consideration and respecting Papagiannopoulos' wisdom. Direct references to Papagiannopoulos are given in the S70K apartment details.
