[2] An extensive refurbishment was completed in 2023 by architects Buckley Gray Yeoman, which included three additional floors bringing its total size to 415,000 sqft.

[4][5] In 2019, the building was purchased by a joint venture between Oaktree Capital Management (majority stakeholder) and Quadrant Estates.

The building had previously been sold by Canary Wharf Group for £200m to German fund manager KanAm Grund in December 2005.

Prior to the 2023 refurbishment, 30 South Colonnade, now YY London, was Thomson Reuters Corporation's European headquarters.

At the time, Tower Hamlets council, the local authority for Canary Wharf said the proposed development would ‘improve the existing office space’ and ‘result in a more environmentally appropriate building’.

The building’s core was shifted and the existing multistorey central atrium was filled to make space to deepen the floor plate and produce additional net internal area.
