30 South Colonnade, also now known as YY London^[1], is a commercial building in Canary Wharf, London. The building was originally designed by Kohn Pedersen Fox and completed in 1991. It was purchased in 2019 by joint venture between Oaktree Capital Management (majority stakeholder) and Quadrant.^[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. The refurbished building stands at 75.5 m (248 ft) tall, with a total of 17 floors – a ground floor, upper ground floor, mezzanine level and 14 upper floors including a rooftop terrace. The building design focuses on sustainability and wellness with extensive on floor terraces, BREEAM Outstanding and WELL Platinum ESG certificates and an all-electric strategy. It has been designed to be net zero in operation.^[3]

YY London primarily provides office space, although following the building’s refurbishment there are also restaurants, communal spaces for events, and food and beverage units at ground floor level.^[4][5]
