Modern Queenslie started as an industrial estate in the 1950s, with housing (a complex of three-storey tenements) added a short time later followed by a primary school – the main streets running through Queenslie were Horndean Crescent, Penston Road, Lonmay Road, Lonmay Path and Blairtummock Road. The nearest Catholic schools were in Cranhill, with nondenominational secondary education provision at Garthamlock (the Queenslie housing was originally connected directly to Garthamlock by a footbridge over the canal until 1969, but was not replaced by an equivalent over the motorway until 1980). At its peak in the 1960s and 1970s Queenslie was a vibrant scheme with a close-knit community with most of the residents employed locally, with factories nearby including Olivetti.
