Our approach

We are committed to re-designing Grosvenor Square in close partnership with both our neighbours, and London communities to bring together the best knowledge to create a new type of urban square that fosters a sense of discovery and wellbeing for both people and planet.

Before introducing Tonkin Liu in March 2020, we already heard from many people. First through an initial survey completed by 1,000 Londoners and then as part of an international Call for Ideas, where many designers, horticulturalists and architects shared creative suggestions for the future of the square.

Informed by these conversations and ideas, we tested an initial set of principles with the community and ran a formal design competition in 2019, which many of the world’s leading landscape and design teams took part in. See where we are in the programme in the timeline below. 

In February 2020, Tonkin Liu were appointed as the lead designer for Grosvenor Square. They were selected as the winners of a formal design competition which included many of the world’s leading landscape and design teams. Their focus on connecting people back to nature, collective storytelling and community involvement were key factors in their success.

Over the past year we offered a range of opportunities for people to be involved in ways and at times that suit them so that they can understand and influence the new designs for Grosvenor Square. We look forward to continuing this conversation next year.

We will continue to regularly share the feedback we gather on the news and events page, mailing list and events so that we are transparent about what we are hearing and how the feedback is having an impact.
