For only the fourth time in its 300-year history, Grosvenor Square is being redesigned.

This Grosvenor-led multi-million-pound transformation, the most significant private investment in public green space in a generation, will demonstrate how green spaces in cities can work harder for nature, and the wellbeing of those who rely on them.  

The rejuvenated space, designed by renowned horticulturalist Nigel Dunnett, leading ecologist Gary Grant and BDP Architects will enhance biodiversity with over c.70,000 new plants, 44 new trees and new wetlands creating a natural haven for wildlife and habitats within Mayfair.  The project will also celebrate and restore the square’s historic memorials, 

Driven by a belief that better engagement makes better places, plans for Grosvenor Square have been developed alongside the community since 2017. Over 7,000 people have fed into the designs, with a particular focus made to encourage young people to share their views, ensuring the proposals reflect the needs, aspirations and values of local residents, businesses and visitors.  

Significantly contributing to our commitment to increase the biodiversity of its green spaces across London, the project will contribute to urban climate resilience, helping to regulate urban heat island effects and mitigate flood risk.  

The redevelopment includes a new learning centre, part funded by The Westminster Foundation offering opportunities for children and adults to learn about biodiversity, nature and the environment, climate change and the square’s rich history. 

This project is part of a multi-year strategic investment wider strategic investment to ensure Mayfair remains a pre-eminent location to work, shop, and live, Grosvenor Square will complement our nearby South Molton project, the West End’s largest mixed-use scheme, set to create a vibrant mix of new offices, retail, cafes restaurants and homes.  

Works on Grosvenor Square are expected to be finished by summer 2026.
