Grosvenor Square Head Gardener

Grosvenor Square Garden (GSG) lies in the heart of our Mayfair Estate.  This 6 acre green space, which celebrates its 300-year anniversary in 2027, is currently undergoing an extraordinary transformation, and is due to reopen in Summer 2026. Led by Grosvenor, this multi-million-pound project is the most significant private investment in public green space in the West End for a generation and will see Grosvenor Square become a fantastic climate-resilient, biodiverse urban garden.

By focussing design on nature and human experience, GSG will become a natural haven within the West End and a green oasis at the heart of a welcoming and vibrant Mayfair. Designed by Professor Nigel Dunnett, there will be a wider range of native and non-native plants and ever changing mosaic of wildflowers, ferns and woodland shrubs will create special moments throughout the year.

A variety of spaces including a large open garden with wild flowering lawn and social ovals allow for different activities, including natural play space, will make garden a place for everyone.

The garden has been designed as one large Sustainable Drainage System such that any water collected within the garden can drain away naturally.  This helps to protect the Square from large volumes of standing water and flash flooding.

Key features of the garden will include:
· 70,000 new plants, 44 new trees, 80,000 bulbs and two new wetlands - creating a haven for wildlife.  
· A new education building - where programmes funded by The Westminster Foundation will offer opportunities for children and adults to learn about biodiversity, climate change and the square’s history.
· Enhanced public amenities - including a new kiosk serving refreshments, public toilets and 300 additional places to sit and relax.

As part of Grosvenor’s commitment to enhancing biodiversity and climate resilience across the green spaces we manage, the reimagined Square will become part of London’s climate infrastructure, bringing together natural solutions and urban greening to help mitigate climate change in the heart of the West End.
