PIA’s operations began from Karachi in 1955 with the establishment of the Pakistan International Airlines Corporation (PIAC).
In 1956–57, a project was launched to construct PIA’s head office near Karachi Airport, aiming to manage all administrative affairs of the new national airline from a single center.
The initial construction of the PIA Building was completed between 1958 and 1959. Designed in a modern architectural style by leading Pakistani and foreign engineers of the time, the building represented contemporary design excellence.
The construction was supervised by the Civil Aviation Department along with PIA’s early Engineering and Finance wings. According to government records from 1958–60, a huge amount was spent on developing PIA’s core infrastructure, which included the Karachi head office, maintenance base, and staff housing colonies.
