The Sky Garden, which was described as a large, free, public viewing space at the top of the building, was part of the justification for the planners allowing such a vast office block to be built on the edge of a conservation area. Computer visualisations shown to the planners included a glade of full-height trees, but the garden as constructed has a slope with ferns and succulents instead.
Free access to the public is provided in 90-minute slots until 18:00, after which the garden is available only to paying customers of the catering facilities.
The Garden has been criticised for these restrictions, and for its extent and quality failing to meet pre-construction expectations. Oliver Wainwright, architecture critic of The Guardian, described it as "a meagre pair of rockeries, in a space designed with all the finesse of a departure lounge".
The City of London Corporation's former chief planner, Peter Rees, who approved the structure, said: "I think calling it a sky garden is perhaps misleading. If people [are] expecting to visit it as an alternative to Kew, then they will be disappointed." In July 2015 it was reported that planners are to consider a landscape architect's alterations to the layout, following claims it is not consistent with illustrations submitted with the original planning application. The 'sky garden' was a key feature in sealing approval for the building, which is situated outside the main cluster of skyscrapers in the City.
