The scheme, which is a joint venture between developers Hammerson and Ballymore, previously included 12 buildings, the tallest of which was planned to be 166-metre (545 ft) tall with 46 floors.

In 2015, the then London Mayor Boris Johnson called in the scheme, which gave him the authority to grant or reject planning permission.

[11] The decision was due on 11 April 2016, with the Mayor's planning officers at Greater London Authority advising him to reject the proposals as they considered the scale of development inappropriate.

[13] In April 2016, the revised plans were withdrawn after Greater London Authority raised concerns over a lack of affordable housing allocation and that the buildings could block sunlight to the surrounding area.

A campaign group called More Light More Power was created, arguing that the current proposals would "mean less sunlight across a very wide area especially in winter months".

[19] Johnson's successor as Mayor, Sadiq Khan, was due to decide whether the proposal will go forward at a hearing on 3 December 2020,[20] which was then given the go ahead.
