Sadler's Wells East

Development of Sadler’s Wells East was announced in June 2018 as part of the Mayor of London’s £1.1 billion "East Bank" project, which was a cultural regeneration initiative within the Queen Elizabeth Olympic Park. Dublin-based firm O'Donnell + Tuomey were commissioned to design the building following their work on the adjacent V&A East Museum. Construction was overseen by the London Legacy Development Corporation, and the completed building became one of the founding institutions to open within the East Bank district. The London Mayor Sadiq Khan attended the opening ceremony on 6 February 2025.

The building is finished with Italian red brick walls, sourced from the Sant'Anselmo works near Venice. The exterior features sawtooth roofing which is designed to reference the industrial heritage of the Stratford area. The interior includes an L-shaped foyer overlooking the Waterworks River The 550-seat auditorium has the same stage dimensions as the main Islington theatre, so productions can easily transfer between the two venues. The theatre includes retractable seating to allow the stage to be more flexibly configured.
