At the heart of the project is the £100 million[1] One Angel Square building, which has been compared to a "sliced egg" due to its distinctive shape and stands at 72 metres (236 feet); it opened in 2013.

In April 2014, a joint venture contract was agreed between The Co-operative and Hermes Real Estate to allow the delivery of new phases.

Inspiration for the branding was taken from SOMA (South of Market) in San Francisco[2] which has been redeveloped in the last three decades.

[3] One Angel Square was the first phase of the NOMA redevelopment scheme and the new support centre for Co-operative Group employees.

[7] Construction began on a new public square and event space in January 2014 and was launched in December 2015.

The square has since been used to home a series of public events, including the annual Sadler's Yard Summer Jam,[citation needed] Sit and Stay at Sadler's Yard dog show,[citation needed] and Summer Beer Thing hosted by The Pilcrow.
