Construction work is now expected to commence in 2029, with completion of the development anticipated in 2033.

The island site by Oxford Circus will deliver 800,000 sq ft of Grade-A office space alongside 102,000 sq ft of retail.

The scheme will also provide 38,000 sq ft dedicated to cultural and creative activities, including a new auditorium and flexible event venues for conferences, product launches and fashion shows, alongside studios and workspaces to support creative, digital and technology businesses.

John Bushell, Principal at KPF said: “We are delighted to have received unanimous planning approval for 33 Cavendish Square. This development will be a distinctive expression of everything that makes the West End exceptional: world-class retail on one of the globe’s most iconic shopping streets, cultural spaces designed to host events from major product launches to conferences, and contemporary workspaces that continue to attract and inspire leading businesses.

“It will enhance the area’s long-standing reputation for creativity, commerce and culture, delivering lasting benefits for businesses, residents and visitors alike.

“This is a thoroughly modern building, designed to resonate with the best of the large buildings along Oxford Street, responding to their composition, scale and materiality. We carried out extensive analysis of the existing buildings to create a scheme that restores a coherent urban form and is an exemplary guardian of embodied carbon.”
