Transforming Grosvenor Square into a world-class public green space that delivers on the Community Priorities.

Set to reopen in summer 2026, Grosvenor Square is being transformed into a world class green space with groundbreaking environmental credentials.

The fourth redesign of the square in its c.300-year history is the largest private investment in public green space in London’s West End in a generation. Engagement with neighbours and other London communities has been at the heart of this redesign and will continue to be so throughout its delivery.

Works to deliver the transformation will start on Monday 9th June 2025.
