The original design for the site, revealed in 2007, was by Richard Rogers Partnership and featured three adjacent towers.

On 27 April 2007, it was revealed that Canary Wharf Group had surprisingly sent a letter to the local council indicating they intend to stop the leasehold on site, and that they would be starting development at Heron Quay on or before August 2008.

This means the development will start years before previously expected, and that North Quay will be constructed after this scheme instead of before it.

Of these, Heron Quays West 1 received outline planning approval in 2013, and is proceeding to detailed design.
