Many of the architectural works present in the city evoke shared memories of people from different generations living in the society. The Plasco building was located at the Istanbul intersection in the center of Tehran. It was one of the first high-rise buildings built in Iran and the middle east. Consequently, it was considered an iconic landmark of Tehran, representing the drive for modernization.
The Plasco building was collapsed on 19 January 2017 during a high-rise fire. The building collapsed after 3.5 hours of burning while the firefighters were still trying to extinguish the fire. As a result, sixteen firefighters were killed in the incident.
The collapse of Plasco in the heart of Tehran was parallel to the collapse of citizens’ memories. Citizens who were carrying different memories of this building for six decades.
When the national building competition for “The New Plasco” was announced in winter 2018, several visions were discussed at Ordibehesht Studio. While the main proposed vision was to flow citizens’ memory from the former building, into the format of a new contemporary building.
The fundamental question was: which characteristics of the former building could carry on to the new building as the symbols of remembrance? Which features of the first Plasco building made contributions to the citizens’ collective memory?
In search of an answer to the raised questions, the citizens’ memory from Plasco was analyzed in the following time periods:
It seems that the most significant and permanent feature that identifies Plasco in the mentioned periods is the geometrical pattern of its façade, the element that was present from the memorable moment of construction till the tragic moment of collapse. It was repeated in all the pleasant and unpleasant impressions of the citizens from the Plasco building.
In designing the replacing building (The new Plasco), the main concept was to define a white frame as an urban monument. This memorial frame is appeared pure and simple in the middle of the urban congestion of Jomhouri Street, while all the happenings and events of the project occur in the heart of it. The façade patterns of the former building are used in the center of the new urban frame as a heritage from the Plasco. This geometrical pattern initiates from the lower levels of the building and extends to underneath the arch. It would be noticed from inside and outside of the project, generating the question in the viewers' minds: what is the reason for the spread of such patterns in the middle of the new structure? Answering this question would consistently remind the importance and role of the former building in citizens’ memories.
