Our Landscape team serve as the lead designer for the design and delivery of this once-in-a- generation transformation to create a stunning urban garden in the heart of London’s iconic west end.


The Square has been modified over the centuries, changing in character from a celebration of horticulture to a memorial landscape with two listed monuments – the Roosevelt Memorial and the Eagle Squadron’s Memorial. With the neighbouring embassy now relocated and its conversion to a hotel complete, things are altogether more relaxed and inviting. By focusing on nature and human experience, Grosvenor Square will once again become a natural haven at the heart of a welcoming and vibrant Mayfair.
Grosvenor Square is the largest of Mayfair’s garden squares and is widely used and deeply cherished. Originally laid out around 1725 it was envisaged as a ‘Wilderness Worke’ - a form of neatly ordered geometric garden for strolling, that brought nature from the countryside into the city, for the wellbeing of city-dwellers. The highlight of the re-imagined garden is undoubtedly the planting. A rich tapestry of textures, colours, forms, and silhouettes provides endless opportunities for visitors to immerse themselves in the joy of the natural world.

The design creates an extraordinary urban garden showing how green spaces can be a joy for nature and people. There are 3 distinct character areas:
• A woodland garden with extensive planting of over 70,000 new plants, diverse seating opportunities, new wetlands and natural play located beneath the canopy of the existing trees. Two new seed pod shaped pavilions provide the community with a café kiosk, educational classroom, accessible public toilets, baby changing facilities and dedicated gardener’s facilities. 9/11 The woodland garden
• The central oval species rich lawn, promenade and sculptural seating resinstates the Square's unique identity. Natural materials and refined finishes appropriate to an elegant and calming geometry have been carefully selected.
• Finally, a formal edge of refurbished ornate railings and gates, enhanced and opened gateways and retained mature hedge supplemented by ecotone planting enhance its Mayfair address.
People of all ages will be able to wander, rest and enjoy recreational activities in a high-quality green space while appreciating the Square’s renewed cultural heritage. The amount of stormwater absorbed by the site is equivalent to: 5,764,000 cups of tea.
