Grosvenor Square

An extraordinary urban garden with ground-breaking environmental credentials

In July 2026, Grosvenor Square was reopened to the public following a radical redesign.

The most significant private investment in public green space in a generation, the transformed square has been designed to demonstrate how green spaces in cities can work harder for nature, and the wellbeing of those who rely on them.  

Featuring 150,000 new plants and bulbs, 44 new trees and new wetlands, designs for the square pay homage to the original 1720s design, reinstating an oval shaped lawn, framed by a new footpath and a surrounding woodland garden.

The square is now home to a new education centre. Run by the London Wildlife Trust and funded by The Westminster Foundation, it offers opportunities for children and adults to learn about nature, biodiversity and the square’s role in addressing climate change.

Blending beauty with biodiversity

Planting across the square has increased from less than one per cent to close to half of the square, creating a natural haven for wildlife and habitats, blending beauty and biodiversity to create a place for visitors and residents to reconnect with nature.

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.

Sustainable Urban Drainage

Sustainable Urban Drainage

Across Grosvenor Square, soil covering an area twice the size of Wembley Stadium's pitch, has been restored, undoing decades of compaction. This allows the ground to breathe, absorb rainwater, and be the best possible home for the 150,000 new plants and bulbs. The square is now part of London's climate infrastructure, combining natural solutions with urban greening to build resilience in the heart of the West End.

Looking to the future

The square includes a new education centre, where programmes funded by The Westminster Foundation and run by London Wildlife Trust are offering opportunities for children and adults to learn about biodiversity, the environment, climate change and the square’s rich history. Providing further community benefits, a new kiosk serving refreshments, public toilets and 300 additional places to sit and relax has been provided.

Marking the start of the transformation of Grosvenor Square, we were joined by the Mayor of London, Sadiq Khan in September 2025, to plant the first of tens of thousands of bulbs set to reimagine the square into an extraordinary urban garden. 

Grosvenor Square will be one of the world’s most outstanding and innovative urban green spaces, responding to the climate emergency whilst inspiring joy, delight and wonder.

Better engagement makes better places

Driven by a belief that better engagement makes better places, plans for Grosvenor Square were developed alongside the community from 2017. Over 7,000 people 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.
