Transformation

A radical re-imagining of an extraordinary urban garden

A radical reimagining: the reopening of Grosvenor Square on 20 July 2026, marked the culmination of an almost decade long journey to reimagine London’s second largest garden square into an extraordinary urban garden.

Over 7,000 people fed into the designs, ensuring that the transformation of the garden reflected the needs, aspirations and values of residents, businesses and visitors alike.

The transformation of Grosvenor Square is part of a wider strategic investment to ensure that Mayfair remains a pre-eminent location to work, shop and live.

A garden that works for nature and people

The redesign of the Square has been guided by the principle of creating a welcoming space that can be enjoyed by all, while demonstrating how green spaces in cities can work harder for nature and the wellbeing of the people that rely on them.  

Planting for the future of Grosvenor Square

As part of our radical reimagination of Grosvenor Square, around 150,000 plants and bulbs were carefully grown for their future home in the heart of Mayfair.
