KILLARNEY CENTRE was no more than 5 years old before its first renovation was undertaken. South and East Wings were added and the entire structure fully-enclosed and climate-controlled.

To accommodate its expansion, the mall was extended over the entirety of the 13-acre plot. The 56-year-old film studio was relocated and then demolished. When the construction dust settled in 1972, the shopping complex had been renamed KILLARNEY MALL.

The KILLARNEY MALL renovation was done as a keeping up measure with several super-sized shopping hubs that were under development on the outskirts of Johannesburg. The first of these, SANDTON CITY, was dedicated in 1973. EASTGATE CENTRE, seen here, opened in 1979.
